Stair Tread Steel Grating

Stair treads, also known as steel grating treads, are made from cross-arranged flat steel bars and crossbars, welded into checkered plates. These steel grating treads are often surface-treated with hot-dip galvanization or electrogalvanization. They are an essential component for steel structure platforms and play a vital role in providing safe access up and down these platforms.

Stair Treads Models: Stair treads are categorized into different types: T1-type, T2-type, T3-type, and T4-type tread plates. The primary distinction lies in the presence of a front guard and perforated side panels, although customization is also possible.

To choose suitable treads, the following considerations can be made: Function and use area are essential factors. When there is high foot traffic on the stairs, it is advisable to opt for treads with a front guard plate for added safety. Alternatively, for cost-effectiveness, treads without a front guard plate can be chosen. Installation methods include bolting or welding. Bolted installation requires the addition of a perforated rear side plate, whereas direct welding eliminates the need for side plates. The production of treads should adhere to national steel ladder production standards. The surface treatment typically involves hot-dip galvanization or painting, with anti-rust paint applied before the topcoat to ensure long-term anti-corrosion protection.

Stair Steel Grating Installation Method: Stair steel grating can be installed using two methods: welding and bolting. For direct welding to the keel steel beam, side panels are not required, resulting in a cost-effective and durable solution, though less easy to disassemble. For bolt-fixed step plates, thicker side panels are necessary, and the installation is done using bolts, allowing for recycling and reusability. Customization is available, enabling the production of steel grating treads in various sizes to match specific stairs. However, it is recommended to consider standard sizes for economic efficiency.

Specifications of Stair Steel Grating: Stair treads can be produced with different anti-slip front guards, and the size can be specified as needed.

Width options: 700mm, 800mm, 900mm, with a minimum width of 600mm. The maximum width is ideally no more than 1200mm. For stairs with single passage, the width between two inclined beams or guardrails should not be less than 600mm.

When stairs frequently experience multiple people crossing at the same time or are designated as evacuation routes, the ladder width should be increased to 1200mm.

The protruding edge of the stair tread should bear a load of 1.5KN. For widths up to 1200mm, the load acts on an area of 100mm×100mm, and the deflection of the treads should not exceed 1/500 of the span of the stairs.

The overlapping part of the vertical projection of two adjacent upper and lower stair treads should not be less than 10mm.

Usage of Stair Steel Grating: Stair treads find wide-ranging applications in various industries, including power plants, water plants, municipal engineering, sanitation engineering, theaters, viewing platforms, and parking lots, where they serve as essential platforms and walkways, providing safety and functionality.
