Steel Stair Treads and Risers - Heavy-Duty Metal Grate Steps for Outdoor Stairs

Elevate safety and longevity in outdoor stairways with our premium Steel Stair Treads and Risers—engineered as heavy-duty metal grate steps designed to withstand the harshest outdoor conditions while delivering reliable performance. As a trusted manufacturer with over 10 years of export experience, we are based in Anping, China, and offer ISO9001-certified galvanized stair steps that adhere to global standards (YB/T4001.1-2007, ANSI/NAAMM, BS4592-1987, AS1657-1985), making them ideal for both residential and commercial applications.

Crafted from high-quality materials including Q235 low carbon steel and SS304 stainless steel, these steel treads and risers feature precision welding and 6mm twist steel cross bars, ensuring exceptional strength, superior load-bearing capacity, and resistance to wear, extreme temperatures, wind, and heavy rain. The surface treatment options—hot-dipped galvanized, painted, or black—provide robust corrosion resistance, protecting against rust and moisture damage for long-lasting outdoor use.

Our metal grate steps are designed for hassle-free installation: each tread comes with holed and grooved side plates to easily attach to stringers, and can be either welded or fixed via grub screws—reducing installation time and labor costs. We also offer a unique range of fittings to enable the easy addition of flat kick and toe boards to standard handrail setups, enhancing safety and security for handrail walkways. Fully customizable to your project’s needs, our treads are available in a wide range of specifications: bearing bar sizes (25x3mm to 75x10mm), bearing bar pitches (12.5mm to 60mm, plus US standard options like 1"x3/16"), and cross bar pitches (38mm, 50mm, 76mm, 100mm, 101.6mm).
