Metal Grating
产品性能介绍
Metal grating is a durable, high-strength material widely used in industrial, commercial, and architectural applications. Fabricated from materials such as carbon steel, galvanized steel, aluminum, and stainless steel, metal grating is designed to provide excellent load-bearing capacity while allowing ventilation, light, and drainage. Its open-grid construction makes it a reliable solution for flooring, walkways, stair treads, mezzanines, platforms, catwalks, and trench covers in environments that demand strength, safety, and long service life.
There are several types of metal grating available, including welded steel bar grating, press-locked grating， 和 expanded metal grating. Welded grating, the most common type, is made by welding perpendicular bars to create a rigid, strong structure. Press-locked grating offers a clean appearance with bars locked into place under high pressure, ideal for architectural use. Expanded metal grating is produced by slitting and stretching metal sheets, forming a mesh-like pattern perfect for lightweight and non-slip surfaces.
Metal grating is valued for its non-slip surface, resistance to deformation， 和 adaptability to custom specifications. It can be manufactured with serrated edges for added slip resistance or coated with anti-corrosion treatments for outdoor or corrosive environments. Galvanized and stainless-steel options offer excellent corrosion resistance, making them ideal for marine, chemical, and food-processing facilities.
From heavy-duty industrial floors to modern urban drainage systems, metal grating is a trusted material that meets strict safety standards and offers long-term value. Its ease of installation, minimal maintenance, and recyclability also contribute to its popularity across a range of industries.
