Construction Platform Catwalk Steel Grating 20mm Hot Dipped Galvanized
Construction Platform Galvanized Heavy Duty Catwalk Steel Grating
Catwalk Steel Grating Introduction
Heavy - duty steel grid is designed and made for heavy load occasions.
Heavy steel grates are formed by the pressure welding process of the twisted button square steel and large size bearing flat steel through high temperature and high pressure.
Due to the particularity of the heavy load steel grid, generally speaking, the heavy steel grid is made of thicker (6mm, 8mm, 10mm) wider flat steel as the bearing flat steel.
Heavy load steel grid plate flat steel spacing is generally 30mm, bar spacing can choose 50mm and 100mm two kinds.
It can be made by pressure welding or pressure lock.
It is suitable for airport, highway, industrial platform, port and other special occasions.

The production technology of heavy steel grates has special requirements. Generally, high quality carbon structural steel or stainless steel is used, which requires high strength and good corrosion resistance. Its chemical composition and mechanical properties should be in line with the GB70088 Q235A or GBL22092 0CrL8Ni9 provisions. Each bearing flat steel and flange flat steel are double bread fillet welding and the welding seam is not less than 3MM; The joint of each bearing flat steel and torsion rod is fully welded; After the production of semi-finished black parts, spatter, welding slag, burr, unsharp edges of four corners and the whole plate must be removed. The heavy steel grid is also very strict on galvanizing requirements. When the thickness of the bearing flat steel is not less than 5MM, the average weight of the zinc layer after galvanizing shall not be less than 610g/㎡; When the thickness of the bearing flat steel is less than 5mm, the average weight of the zinc layer after galvanizing shall not be less than 460g/㎡. The quality and requirements after galvanizing shall conform to the latest standard of "hot dip galvanizing" GB/T13912-2008.
Catwalk Steel Grating Construction
The most important characteristic of heavy steel grid is that it has a great load capacity and the strongest impact resistance.It is recommended to use toothed steel grates to provide better friction.It is the first choice for places with large load and many vehicles.The best manufacturing method is pressure lock, which can effectively prevent the tilt instability of bearing flat steel.Avoid deformation of load flat steel.
Catwalk Steel Grating Application
Steel grates are suitable for alloys, building materials, power plants, boilers. Shipbuilding.
Petrochemical, chemical and general industrial plants, municipal construction and other industries, with ventilation, light, anti-skid, strong bearing capacity, beautiful and durable, easy to clean, easy installation and other advantages.
Steel plate has been widely used in all walks of life both at home and abroad, mainly used for industrial platform, staircase pedal, banister, channel floor, railway bridge service, high tower platform, the drain cover, manhole covers, road barrier, three-dimensional parking lot, organs, schools, factories, enterprises and institutions, the stadium fence, garden villa, also can be used as a residence outside the window, balcony guardrail, highway, rail barrier, etc.
The method of welding fixation is:
the fillet welding with the length of the weld not less than 20mm and the height not less than 3mm on the first flat steel at each corner of the steel grid plate.
When ordering mounting clips, please specify the type, quantity and material required.
The installation can be fixed by welding and clamping.
Welding fixation is suitable for permanent parts that do not need to be disassembled, such as the platform around the equipment, and the installation clip has the characteristics of not destroying the zinc layer and convenient disassembly.
Mounting clamps are suitable for all series of steel grates, which are composed of upper clamps, lower clamps and M8 bolts.
The method of fixing the installation clip is: each plate adopts at least four sets of installation clip, and it is best to install several more supports on the larger plate span.
Stainless steel mounting clips are available to meet customer requirements.
Package delivery:
Delivery when will we have a professional inspectors to check the quality of the product is unqualified, such as qualified will paste the qualified product certificate, and then fixed by shipping packaging, packaging with the steel plate on the metal tray, and then fixed with metal packing tape, finally wrapped by plastic film packaging, general each pallet packing 1-2 tons of cargo, in order to convenient for unloading and storage after the arrival of the goods. The unqualified products will be recalled by our quality inspector.
