Hot formed hollow sections (HFHS), including square and rectangular hollow tubes, are widely used for industrial flooring, walkway platforms, stair treads and structural floor framing. To enhance friction and prevent slip hazards under foot traffic or equipment load, the following mainstream anti-slip treatments are specially applied for flooring scenarios:
1. Mechanical Surface Texturing (Physical Anti-slip Treatment)
This permanent physical treatment creates rough irregular surfaces to improve friction without adding extra surface layers, compatible with raw hot-finished hollow sections.
- Shot Blasting: High-speed steel shots impact the tube surface to form uniform micro rough textures. It improves slip resistance effectively, serves as an ideal pretreatment for subsequent painting, and suits outdoor flooring, factory walkways and bridge platforms.
- Laser Texturing: High-precision laser engraves regular anti-slip micro-patterns on the hollow section surface. It features stable friction coefficient, neat appearance and high wear resistance, applicable for high-standard industrial flooring and precision equipment platforms.
- Embossing: Custom anti-slip raised textures are rolled on flat contact surfaces of hollow sections during hot forming, providing durable skid resistance for heavy-load flooring.
2. Industrial Anti-slip Coating (Chemical Coating Treatment)
Resin-based coatings mixed with hard abrasive particles (aluminum oxide, silicon carbide or silica sand) are evenly painted on HFHS flooring surfaces. The protruding particles deliver continuous anti-slip performance, with excellent adhesion on hot formed steel substrates.
- Epoxy Anti-slip Coating: Featured with strong adhesion, chemical corrosion resistance and low cost. Perfect for indoor factory floors, warehouse platforms and dry working walkways.
- Polyurethane Anti-slip Coating: Outstanding weather resistance, flexibility and waterproof performance. Suitable for outdoor flooring, marine platforms and humid environments with temperature changes.
- High-temperature Resistant Anti-slip Paint: Designed for special industrial flooring with high temperature exposure, retaining friction stability under extreme working conditions.
3. Detachable Anti-slip Auxiliary Accessories
Easy-to-install auxiliary anti-slip parts are fixed on HFHS flooring surfaces, suitable for temporary usage or scenarios requiring frequent maintenance.
- Anti-slip Inserts: Rubber or high-strength plastic inserts embedded on hollow section surfaces. Soft anti-slip touch, corrosion resistance, ideal for public facility flooring and pedestrian walkways.
- Abrasive Anti-slip Tapes & Strips: Self-adhesive anti-slip strips with mineral grit, commonly pasted on edge areas of steel flooring, stair treads and ramp sections for local anti-slip reinforcement.
4. Hot-dip Galvanization + Secondary Roughening
For outdoor corrosive flooring environments, hot formed hollow sections are firstly hot-dip galvanized for anti-rust protection. Then surface roughening treatment or thin anti-slip coating is processed on the galvanized layer to eliminate the smooth galvanized surface and balance anti-corrosion and anti-slip performance.
Selection Guidelines for Flooring Usage
- Heavy-load & High-traffic flooring: Prioritize shot blasting + epoxy anti-slip coating for long-term durability.
- Outdoor & humid flooring: Adopt polyurethane coating or galvanization combined with surface texturing.
- High-precision & aesthetic flooring: Choose laser texturing for uniform and neat anti-slip patterns.
- Temporary or low-budget projects: Apply anti-slip tapes and rubber inserts.
