Steel Grating: Premium Solution for Industrial & Commercial Applications

Our steel grating is a high-performance open-framework product tailored for both industrial and commercial scenarios. It integrates exceptional load-bearing capacity, durability, and versatility, serving as an ideal choice for flooring, platforms, stair treads, trench covers, and more. Crafted through advanced production methods and strict quality control, it meets the diverse demands of complex working environments.

Core Production Technologies

We adopt two mature production methods to cover different application requirements, ensuring both stability and flexibility:

• Machine Pressure Welding: High-voltage resistance welding machines equipped with strong electric power and hydraulic pressure are employed. Cross bars are securely embedded into flat steel, forming robust and stable weld joints. This method guarantees consistent quality, high production efficiency, and excellent structural integrity, suitable for large-batch standard products.

• Manual Production: Designed for custom requirements and specialized applications. It offers high flexibility in adjusting dimensions, structures, and processing details, effectively meeting non-standard demands from specific projects.

Product Material Composition

The steel grating is composed of high-quality components, ensuring reliable performance and long service life:

• Flat Steel: Serves as the primary load-bearing element, responsible for bearing main loads. Its material and specification selection are determined based on the required load capacity of the application scenario.

• Twist Steel (Cross Bars): Functions as the connecting and stabilizing component, maintaining the spacing of flat steel and enhancing the overall rigidity of the grating. Typically made of twisted square steel, round steel, or flat steel.

• Pattern Plate (Optional): An optional surface treatment component that can be added according to anti-slip or aesthetic needs, further improving the product's practicality.

The overall structure is an open steel framework, where load-bearing flat steel and cross bars are welded or pressure-locked at precise intervals. Common material options include carbon steel and stainless steel, adapting to different corrosion resistance and strength requirements.

Standard Manufacturing Process

The production of pressure-welded steel grating follows a strict and precise process flow to ensure product quality:

1. Precision Arrangement: Load-bearing flat steel and cross bars are arranged according to standard spacing or custom requirements, ensuring accurate positioning to lay a solid foundation for subsequent welding.

2. High-Strength Welding: Welding is performed using 200-ton hydraulic resistance welding equipment. The strong pressure and stable current ensure that each weld joint is firm and consistent, avoiding weak joints.

3. Secondary Processing & Packaging: After welding, the products undergo secondary processing such as cutting (to meet specific size requirements) and opening (for installation and connection). Finally, they are packaged according to transportation and storage standards to prevent damage during circulation.
