Product Introduction
Slip-resistant raised expanded grating sized for catwalks and elevated walkways. One-piece steel, free-draining diamonds, hot-dip galvanized. Light yet strong decking for safe overhead access.
Product Introduction
Catwalk expanded metal grating is a lighter member of the expanded grating family, tuned specifically for elevated pedestrian access ways. Catwalks, mezzanine walkways and inspection platforms need decking that is strong enough to carry workers and tools yet light enough to keep structural steel costs down, and one-piece expanded grating delivers exactly that balance. Made by expanding steel plate into a continuous diamond mesh, it has no welds to fail and provides a naturally slip-resistant, free-draining surface ideal for the wet, dusty or oily conditions found high above plant floors. Zhongman supplies catwalk grating in hot-rolled carbon steel with hot-dip galvanizing for long outdoor and industrial life, in panels and pre-fabricated walkway sections cut, formed and banded to suit standard support spacings and handrail systems.
Key Features & Advantages
Catwalk grating combines safety and economy. The raised diamond pattern grips boots even when surfaces are wet or coated with oil, dust or ice, sharply reducing fall risk on elevated routes. Open diamonds let water, debris and small objects fall through so the walkway drains itself and stays clear. One-piece construction means there are no welded joints to crack under the constant flexing of foot traffic, and the panels are lighter than welded bar grating, easing installation and lowering the load on supporting steel. Hot-dip galvanizing protects against corrosion in outdoor and chemical atmospheres. Panels can be sized to common bearer spacings so they install quickly, and banded edges plus optional toe plates help meet walkway safety codes.
Specifications & Options
Zhongman builds catwalk grating in pedestrian-rated weight classes, typically from about 2.0 to 4.5 lb/ft², with larger diamond sizes around 1" to 2" short-way for an open, free-draining deck. Open areas of roughly 40% to 70% maximise drainage and light penetration while still giving secure footing. Standard material is hot-rolled carbon steel, finished with hot-dip galvanizing; painted and mill finishes are also available. We supply flat panels or fully fabricated walkway sections cut to length, formed with turn-ups or toe plates, and perimeter-banded for clean, safe edges. Custom widths match handrail and stringer layouts, and we can provide load and span guidance so the chosen panel safely meets the deflection limits required for personnel walkways.
Applications & Industries
Catwalk expanded grating is found wherever people need safe overhead access. Process plants in oil and gas, chemical, power, food and water treatment use it for catwalks running between vessels, conveyors and equipment, and for inspection and maintenance platforms. It decks mezzanine walkways in warehouses and factories, access bridges over machinery, and stair treads and landings on industrial stairways. Outdoor structures such as tank farms, silos, cooling towers and offshore platforms rely on its drainage and corrosion resistance. Stadiums, transit hubs and commercial buildings use it for service catwalks above ceilings and around mechanical plant. Anywhere a light, strong, slip-resistant and self-draining elevated walkway is required, catwalk grating is the standard solution.
Why Choose Zhongman
Zhongman manufactures catwalk grating to walkway-grade standards, expanding steel plate in-house and finishing it through our own cutting, forming, banding and hot-dip galvanizing lines. We size panels to your bearer spacing and handrail layout so installation is fast and joints align cleanly, and we add toe plates, turn-ups and banded edges to help your project meet safety codes. Our engineers provide load and deflection data so you can confirm the grating suits personnel loading over the intended span. Direct material sourcing keeps catwalk grating affordable, and our export team handles inspection, secure crating and global shipping of panels or prefabricated walkway runs. For safe, economical elevated access, Zhongman delivers reliable catwalk grating built to spec.
