Core Structure and Materials
Load-bearing flat steel: The main load-bearing component, specifications such as 25/30/40mm high, 3–5mm thick; available in flat, serrated (anti-slip), and I-beam types.
Crossbars: Commonly used 5×5 twisted square steel, spacing 50/100mm, to fix the flat steel and enhance stability.
Materials:
Carbon steel Q235B: Hot-dip galvanized (60–85μm), outdoor lifespan 15–20 years, high cost-effectiveness.
Stainless steel 304/316L: Strong corrosion resistance, suitable for chemical, food, and coastal applications.
Aluminum alloy: Lightweight, used in special scenarios.
Mainstream Types
Welded Steel Grating
Flat steel bars are resistance welded to crossbars. High strength, low cost, and most commonly used.
01
Press-locked Steel Grating
Flat steel bars are perforated, and crossbars are pressed in and interlocked. No weld points, flat surface, suitable for irregular/high-precision applications.
02
Serrated Steel Grating
Flat steel bars have serrations for slip resistance. Used for stair treads and wet/oily platforms.
03
Heavy-duty Steel Grating
Flat steel bars are thickened (6–12mm) with denser spacing. Load capacity ≥10kN/㎡. Used for ports and driveways.
04
Stair Treads
Special stair treads with anti-slip front guard plates, conforming to GB4053.2 standard.
