Applications
• Industrial flooring & platforms: factories, catwalks, access ramps, mezzanines
• Transport: truck beds, trailer decks, toolboxes, firetruck steps, ambulance interiors
• Marine: gangways, engine rooms, hatch covers (5754/5083/5086)
• Architecture & interior: wall cladding, kick plates, counters, retail fixtures
• Cold rooms & food: hygienic, easy-clean panels and thresholds
• Stairs & walkways: public buildings, stadiums, stations
• Protection: door/wall guards, equipment covers, loading bay edges
Alloy Selection Guide (Quick Comparison)
• 1050 / 1060 / 1100 (Commercially Pure) — Best formability, good conductivity; light duty, décor, cladding; indoor/general use.
• 3003 / 3105 (Al-Mn) — Workhorse tread; good corrosion resistance & workability; vehicles, building floors, general industrial.
• 5052 / 5754 / 5083 / 5086 (Al-Mg) — Marine-grade corrosion resistance with higher strength; docks, trailers, outdoor & coastal.
• 6061 / 6082 (Al-Mg-Si) — High strength & weldable; industrial floors, ramps; limited tight-radius forming vs 3xxx/5xxx.
Tempers: H114 (tread), H22/H24 (work-hardened), H32/H34, T6 (solution-treated & aged for 6xxx).
Select alloy/temper based on load, span, environment, and fabrication (bending, welding, finishing).
FAQs
Q1: 5-bar vs diamond—how to choose?
5-bar offers excellent multi-directional grip for floors and ramps; diamond (propeller/1-bar) is popular for decorative panels, toolboxes, and where a bold look is desired.
Q2: What thickness should I use for floors?
Light traffic walkways: 2.0–2.5 mm; forklifts/vehicular: 3.0–6.0 mm depending on support spacing. Tell us your span & load—we’ll size it.
Q3: Which grade for marine or outdoor use?
5754/5083/5086 are typical for marine/corrosive environments. For general trucks & buildings, 3003/5052 work well.
Q4: Can you supply bright/mirror tread plate?
Yes—Tread Bright (3003 H22) and polished finishes are available; we can also anodize (clear/colored) for harder, decorative surfaces.
Q5: Are the listed sizes the only ones?
No—cut-to-size and non-standard lengths/widths are available. We also supply coil for continuous applications.
Q6: How do you pack for export?
Moisture-barrier paper + PE film (on request) + corner protectors + fumigated wooden pallets/crates, steel strapping, fork-friendly.
Q7: Do you provide MTC and compliance docs?
Mill Test Certificates and compliance statements (e.g., RoHS/REACH) are available per order.
Q8: What’s the difference between “on the plain” thickness and overall?
“On the plain” excludes lug height. Overall measured thickness at the lug is higher than the plain base sheet.
