1. Overview of Welded Steel Grating

Welded steel grating is a robust and durable metal grating type formed by welding bearing bars and crossbars together. It is widely used in industrial, commercial, and public infrastructure applications due to its high strength, load-bearing capacity, and resistance to impact. Welded steel grating provides excellent drainage, ventilation, and slip resistance, making it ideal for walkways, platforms, stair treads, and drainage covers.

2.1 Types of Welded Steel Grating

Welded steel grating comes in various designs and configurations to meet different application needs:

1. Plain Welded Steel Grating

This type features smooth bearing bars and is commonly used in industrial settings where slip resistance is not a primary concern.

2. Serrated Welded Steel Grating

Serrated welded steel grating has notched bearing bars that provide enhanced slip resistance, making it suitable for wet or oily environments.

3. Heavy-Duty Welded Steel Grating

Designed for high-load applications such as bridges, airport runways, and loading docks, this type features thicker and wider bearing bars for maximum strength.

4. Stainless Steel Welded Grating

Made from stainless steel, this type is highly corrosion-resistant and ideal for harsh environments like chemical plants and marine applications.

2.2 材料组成

• 碳钢: Standard material for welded steel grating, often galvanized for corrosion resistance.

• 不锈钢: Used for high-corrosion areas, available in grades 304 and 316.

• 轴承杆: Rectangular or I-shaped, made from high-strength steel.

• 横杆: Typically round or twisted rods, providing structural support.

• 表面处理: Hot-dip galvanized, painted, or untreated.

2.3 Surface Treatments

• Hot-Dip Galvanizing: Provides long-term corrosion protection.

• 粉末涂装: Enhances appearance and weather resistance.

• 轧制表面: Standard untreated steel finish for cost-effective applications.
