Steel Grating Specifications
Steel grating is a durable and versatile product commonly used in industrial, commercial, and infrastructure projects. It is made up of bearing bars and cross bars that are welded together to form a strong, open-grid structure. The design and specifications of steel grating can vary widely depending on the intended use, load capacity, and environmental conditions.
Bearing Bars
The main structural components of steel grating are the bearing bars, which are responsible for supporting the weight or load placed on the surface. These bars are usually manufactured from rolled steel, sheet metal, or slit steel, and often have an I-shaped cross-section for added strength. To enhance safety, the top surface of the bearing bars may be serrated or patterned to prevent slipping, especially in wet or oily environments.
Materials
Steel grating is typically produced using either mild carbon steel or stainless steel. Mild steel is preferred for applications where high strength and cost-effectiveness are important, such as in factories, warehouses, and walkways. Stainless steel, particularly grades 304 and 316, is ideal for areas exposed to moisture, chemicals, or corrosion, offering long-lasting durability and minimal maintenance.
Finish Options
To improve longevity and aesthetics, steel grating is often coated with protective finishes. Common options include painting, which provides a clean and customizable look, and galvanizing, where a layer of zinc is applied to prevent rusting. Some grating is supplied in a raw state, allowing the end user to apply their own finish. Hot-dip galvanizing is a popular method among manufacturers, as it offers excellent corrosion resistance and a uniform coating that enhances the product's lifespan.
Steel Compression Double Seal Crimp Flange Fittings
The crimped thread joint is composed of an inner metal ring, the root of turnup flange, an union, and positive and negative threaded sleeves; the connection type is divided into union connection and positive and negative threaded sleeve connection; reinforced steel wires or glass fibres are flipped 180 degrees at the root of the turnup flange.
