Maintenance Tips

RECOMMENDED MAINTENANCE SCHEDULE

High-Traffic Facilities (250+ entries per day):
• Daily surface cleaning
• Weekly frame and well cleaning
• Bi-weekly system inspection

Moderate-Traffic Facilities (50-250 entries per day):
• Surface cleaning 2-3 times per week
• Monthly frame and well cleaning
• Monthly system inspection

Seasonal Considerations:
During winter months (November through March), increase cleaning frequency by 50% due to increased tracking of salt, sand, moisture, and debris.

DAILY SURFACE MAINTENANCE

Carpet Insert Cleaning:
Vacuum thoroughly using a commercial-grade vacuum cleaner. For optimal results, ensure the vacuum head moves lengthwise along the grill components to maximize soil extraction from both the carpet fibers and aluminum channels. The vacuum head should have adequate depth to reach into all surface variations.

Vinyl Insert Cleaning:
Begin with vacuuming to remove loose debris. Follow with damp mopping using a mild soap and water solution. Allow the surface to air dry completely before heavy foot traffic resumes.

Stiff Brush Cleaning:
For dry debris accumulation, use a stiff-bristled brush to dislodge particles before vacuuming. This is particularly effective for sand, salt crystals, and dried mud.

SPOT CLEANING PROCEDURES

General Spill Protocol:
Address spills promptly to prevent staining and reduce slip hazards. Work from the outer edge of the spill toward the center to avoid spreading the contamination.

Dry Spills:
Brush debris into a dustpan or vacuum immediately.

Liquid Spills (Small):
Blot with absorbent material (clean cloth or paper towels). Follow with a damp cloth using mild soap and water. Blot dry with a clean cloth.

Liquid Spills (Large):
Use a wet/dry vacuum for rapid extraction. For stubborn residue, a hot water extraction machine may be employed on carpet inserts.

Chewing Gum Removal:
Remove gum promptly before it hardens. Apply a commercial gum removal gel according to manufacturer directions. Use a plastic spatula to lift the gum gently—avoid metal tools that may scratch aluminum surfaces. The cleaned area may appear slightly lighter than surrounding material; this is normal.

FRAME AND WELL CLEANING

Frequency:
Weekly during winter months; monthly during other seasons. Adjust based on your facility’s specific traffic patterns and environmental conditions.

Preparation:
Before lifting the mat modules, thoroughly vacuum the surface to remove loose debris. This prevents material from falling into the well during removal.

Module Removal:
Carefully lift individual mat sections from the recessed frame. If your system features hinged connections, handle with care to avoid stressing or damaging the hinge mechanisms. Roll the mat sections loosely for temporary storage during cleaning.

Well and Frame Cleaning:
Vacuum the recessed well thoroughly to remove all accumulated dirt, debris, and moisture. Wipe down the aluminum frame with a solution of mild soap and warm water using a mop, sponge, or cloth. For stubborn residue, a soft-bristled brush may be used.

CRITICAL:
Ensure the recessed well is completely dry before reinstalling mat modules. Any remaining moisture or debris can cause the mats to warp, create uneven surfaces, and lead to long-term structural problems. If water drainage systems are present, verify they are functioning properly and free from blockages.

ALUMINUM SURFACE CARE

Standard Cleaning:
Clean aluminum rails and components with warm water and a pH-neutral soap. Rinse thoroughly with clean water and allow to air dry completely.

Stainless Steel Options:
For facilities that have selected stainless steel components, a specialized stainless steel cleaner may be applied to maintain surface luster. Products such as Simple Green or Sheila Shine are suitable options. Always follow the product manufacturer’s application instructions.

PERIODIC DEEP CLEANING

Frequency:
Quarterly, or when visual inspection indicates excessive soil buildup.

Hot Water Extraction (Carpet Inserts):
Professional-grade hot water extraction equipment provides the most thorough cleaning for carpet inserts. This process removes embedded soil and helps restore the carpet pile. Ensure inserts are completely dry before reinstallation—typically 24 hours.

Alternative Methods:
Dry extraction compounds may be used between hot water extraction sessions. Apply the cleaning compound with a stiff brush, allow brief dwell time for soil absorption, then vacuum thoroughly.

Solution Brush Extraction:
Mechanical cleaners with counter-rotating brushes can introduce cleaning solution and extract soiled water simultaneously. This method is effective but requires careful attention to moisture extraction to prevent premature re-soiling.

SYSTEM INSPECTION PROCEDURES

Visual Assessment:
Verify that all mat panels are level and flush with the surrounding floor surface. Check for any warping, lifting edges, or uneven sections that could create trip hazards.

Hinge and Connection Points (If Applicable):
For systems with rubber or mechanical hinges, inspect each connection point to confirm secure attachment and proper function. Replace any damaged or worn components immediately.

Debris Accumulation:
Confirm that no excessive buildup exists beneath the mat modules or within drainage systems. Even small amounts of debris can cause gradual warping over time.

Insert Condition:
Examine carpet or vinyl inserts for excessive wear, staining, or damage. Plan for replacement of inserts that no longer perform effectively.

PROHIBITED CLEANING METHODS

To prevent damage to your system, NEVER use:

• Steam cleaners or steam settings on vacuum cleaners (can damage adhesives and cause warping)
• Wax or polish products (creates slip hazards)
• Abrasive cleaners or scrubbing pads (scratches aluminum)
• Chlorinated solvents or bleaching agents (degrades materials)
• High-pressure washing on installed modules (can force water beneath mats)
• Excessive force when using spatulas or scrapers (damages surfaces)

FAQs

The carpet insert versions (nylon or polypropylene) feature replaceable carpet or vinyl inserts in aluminum tread rails, offering excellent dirt trapping and a traditional mat appearance. The UFM38 SSS stainless steel grating version features solid Type 304 stainless steel construction with no fabric, providing ultimate durability (500 lb. rolling load), easy sanitization for healthcare/food service, superior drainage, and a premium appearance. The SSS also comes with a 5-year warranty vs. 2-year for carpet versions.

Nylon Carpet: Best for indoor commercial environments (offices, retail, banks) with primarily dry debris. Professional appearance, excellent dirt trapping, comfortable underfoot. Heavy-Duty Polypropylene Carpet: Best for high-traffic areas, outdoor-to-indoor transitions, and all-weather conditions. Handles wet conditions, snow, and heavy soil loads. More durable than nylon in harsh environments. Vinyl Serrated: Best for all-weather applications, wet environments, and food service areas. Easiest maintenance (just hose down), no fabric to absorb moisture, longest-lasting insert option. Stainless Steel Grating: Best for high-end lobbies, healthcare facilities, food service, industrial environments, and anywhere requiring ultimate durability, easy sanitization, or maximum drainage.

Yes! The aluminum frame is corrosion-resistant and suitable for outdoor use. For insert selection: heavy-duty polypropylene carpet or vinyl serrated inserts perform best in outdoor or outdoor-to-indoor transition applications. The stainless steel grating (SSS) is also excellent for outdoor use with superior drainage. Nylon carpet is better suited for primarily indoor applications.

Yes, the UFM38 system is designed to comply with Section 4.5 of the ADA Accessibility Guidelines (ADAAG). The closely spaced inserts (≤1/2" openings) prevent crutch tips and canes from catching. Surface-mounted versions include ADA-compliant tapered vinyl ramps for proper transitions.

For optimal dirt and moisture control, we recommend a minimum of 10 feet in the primary direction of travel (this also qualifies for LEED IEQ Credit 5). The mat should be at least as wide as the entrance to capture all traffic. We provide custom sizing to fit your exact entrance dimensions. Contact us with your measurements for a custom quote.

The UFM38 is designed for level installations. For sloped entrances, contact us to discuss your specific application and determine if a custom solution is feasible.

For flush installation with the standard aluminum angle frame (1/2" x 1" x 1/8"), you need a minimum recess depth of approximately 7/8" total (3/8" mat thickness + 1/2" frame depth). For the embedded frame option (7/8" deep), total recess depth is approximately 1-1/4". The substrate must be flat and level (±1/8" in 10 feet per ACI 302).

Yes! The surface-mounted option requires no floor cutting. We provide tapered vinyl ramps on both edges for ADA-compliant transitions. This is perfect for retrofit applications, rental properties, or situations where floor modification isn't feasible. Installation is quick (often same-day) and the system can be relocated if needed.

s! The UFM38 is an excellent drop-in replacement for existing 3/8" entrance mat systems. This is our "shallow recess upgrade" option. It works with existing recess dimensions with minimal or no modification, maintains existing door clearances, and provides improved performance over worn systems. This is a cost-effective upgrade path without major construction.

Absolutely! The UFM38's modular construction allows us to create custom configurations for virtually any entrance shape or size. We can accommodate columns, door frames, angled walls, curved sections, and other architectural features. We provide shop drawings for your approval before fabrication. Contact us with your specific requirements.

For recessed installations, the aluminum frame is anchored to the concrete substrate every 18" to 24" (anchors provided by installer). For surface-mounted installations, anchoring is done as required for stability. The SSS stainless steel version includes hidden lockdown devices with concealed fasteners spaced maximum 2'0" on center for secure installation.

While professional installation is recommended to ensure proper fit, alignment, and anchoring, facility maintenance teams with basic construction skills can install the surface-mounted version. Recessed installations require more expertise for proper frame installation and anchoring. We provide detailed installation instructions and technical support. The substrate must be properly prepared (flat and level per ACI 302).

Maintenance is simple and varies by insert type: Carpet Inserts: Vacuum regularly to remove surface dirt. For deeper cleaning, roll up the mat (easy with ball and socket hinges) to clean the pit area beneath. Spot clean carpet as needed. Replace inserts when worn. Vinyl Inserts: Sweep or vacuum loose debris, then damp mop or hose down. Roll up mat periodically to clean beneath. Stainless Steel Grating: Sweep or vacuum daily. Hose down or pressure wash as needed. Roll up sections to clean pit area. Virtually maintenance-free.

nsert lifespan varies based on traffic level and conditions: Nylon Carpet: 2-3 years in typical commercial applications Heavy-Duty Polypropylene Carpet: 3-5 years in high-traffic applications Vinyl Inserts: 5-7+ years with minimal wear Stainless Steel: 10-15+ years (typically never needs replacement) The beauty of the UFM38 system is you replace only the worn inserts, not the entire mat, keeping costs low.

Yes! This is one of the UFM38's best features. The ball and socket hinge design allows you to easily roll up mat sections for thorough cleaning of the pit area beneath. No special tools required. This prevents buildup of debris and moisture that can cause odors and bacteria growth. Simply access an edge and roll up from one end.

No. The 6063-T6 extruded aluminum is naturally corrosion-resistant and requires no painting, sealing, or special treatments. The vinyl hinges require no lubrication. The frame maintains its appearance and performance for 10-15+ years with normal use. This is a true low-maintenance system.

The SSS version is extremely low-maintenance. Sweep or vacuum regularly to remove loose debris. Hose down or pressure wash as needed (the open grating design provides excellent drainage). Roll up sections periodically to clean the pit area. The #4 satin finish can be maintained with standard stainless steel cleaners if desired, though this is typically not necessary. No fabric means no moisture absorption, odors, or stains.

The UFM38 is built for commercial-grade performance: Standard versions: 350 lbs. per wheel rolling load SSS stainless steel version: 500 lbs. per wheel for 1,000 passes with no visible damage All versions: 1,500 lbs/sq. ft. uniform floor load This handles delivery carts, hand trucks, wheelchairs, pallet jacks, and all pedestrian traffic including emergency evacuations.

Yes! The UFM38 performs excellently in wet conditions. The tread rail design with 1-1/2" spacing provides aggressive scraping action for snow and slush. Optional drainage holes (or open grating on SSS version) prevent water pooling. Heavy-duty polypropylene carpet, vinyl inserts, or stainless steel grating are best for wet/snowy conditions. The non-slip surfaces maintain traction even when saturated.

The aluminum frame and structure typically last 10-15+ years with proper maintenance. Insert lifespan varies: nylon carpet 2-3 years, polypropylene carpet 3-5 years, vinyl 5-7+ years, stainless steel 10-15+ years. Because inserts are replaceable, you can extend the system's life indefinitely by replacing only the worn components.

No. The vinyl hinge system eliminates the metal-to-metal rattle common in cheaper aluminum mat systems. The vinyl cushion pads provide quiet operation even under heavy foot traffic. This makes the UFM38 suitable for noise-sensitive environments like libraries, healthcare facilities, and professional offices.

No. When properly installed with appropriate anchoring, the UFM38 stays securely in place. Recessed versions are anchored every 18-24". Surface-mounted versions include proper anchoring for stability. The SSS version includes hidden lockdown devices for additional security. The system is designed to remain stable even under heavy wheeled traffic.

The UFM38 is positioned as the "high-quality, low-cost alternative." While initial cost may be higher than cheap rubber mats, the total cost of ownership is significantly lower due to: Longer lifespan (10-15+ years vs. 3-5 years for rubber) Lower maintenance costs (easy cleaning, no professional services needed) Replaceable inserts (replace only what's worn, not entire mat) Protection of interior flooring (prevents expensive damage and refinishing) Reduced cleaning costs (keeps facility cleaner longer)

he UFM38 system includes: Custom-fabricated aluminum mat sections Aluminum frame (angle or embedded, based on your selection) Your choice of inserts (carpet, vinyl, or stainless steel) Vinyl hinges and cushion pads Black vinyl filler (if required for custom fit) Corner connectors and splice plates (for large installations) Hidden lockdown devices (SSS version) Tapered vinyl ramps (surface-mounted version) Not included: Anchors (provided by installer), installation labor, pit liner (optional), drainage components (optional, under separate contract).

Replacement inserts are cost-effective compared to replacing an entire mat system. Pricing varies by insert type and size. Contact us for replacement insert pricing. Many customers find it economical to keep a spare set of inserts on hand for quick replacement during peak traffic seasons.

: Yes! Standard versions: 2-year limited warranty on aluminum frame, vinyl ramps, and vinyl inserts SSS stainless steel: 5-year limited warranty on grating and framesWarranty covers defects in materials and workmanship when properly installed and maintained. Normal wear of replaceable components (carpet/vinyl inserts) is not covered.

Yes! The UFM38 can contribute to multiple LEED credits: MR Credit 4 (Recycled Content): 32.5% post-consumer recycled aluminum (SSS version: ≥80% post-consumer + ≥15% pre-consumer) IEQ Credit 4.3 (Low-Emitting Materials): Meets California Specification 01350 for low VOC emissions IEQ Credit 5 (Indoor Chemical & Pollutant Source Control): Permanent entryway system ≥10 feet in primary direction of travel We provide documentation to support your LEED submittal.

Yes! Aluminum is 100% recyclable with full material value recovery at end of service life. This supports circular economy principles and reduces long-term environmental impact. The UFM38 is an environmentally responsible investment.

Standard aluminum frame/tread rails: 32.5% post-consumer recycled content SSS stainless steel: ≥80% post-consumer + ≥15% pre-consumer recycled content (typically exceeds 95% total) All materials are 100% recyclable at end of service life.
