Q235 Carbon Steel Platform Steel Grating Galvanized Serrated Square Shape
Q235 Carbon Steel Galvanized Serrated Platform Catwalk Steel Grating
Catwalk Steel Grating Introduction
Serrated steel grillings are welded with serrated flat steel on one side. Besides the characteristics and uses of ordinary steel grillings, they also have strong anti-skid ability, especially suitable for wet and slippery places, offshore oil production platforms, etc.
The sawtooth steel grating adopts hot dip galvanized surface treatment, which has strong rust resistance.
The gutter cover and frame can be connected by hinge, which is safe and easy to open.
Tooth flat steel (general material is Q235) common models are generally 235 253 255 303 305 323 325 403 404 405 and other specifications.
The difference between toothed flat steel and ordinary flat steel is that there are uneven tooth marks on one side of the flat steel.
Mainly lies in the skid.
We mainly use the longitudinal shear flat steel, and a steel plate cut.
Twist steel (also called twisted square steel), there are generally 5X5, 6X6, 8X8 square steel, twisted bar.

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.
Catwalk Steel Grating Advantages
(1) It is welded with serrated flat steel on one side. In addition to the characteristics and uses of ordinary steel grates, it also has strong anti-skid ability, especially suitable for wet and slippery places, offshore oil production platforms, etc.;
(2) the use of hot dip galvanized surface treatment, with a strong rust resistance,30 years free of maintenance and replacement.
This product can be used as a hinge connection between the drain cover and the frame, which is anti-theft, safe and easy to open.
(3) the use of high strength carbon steel, so that the steel grid has a very high strength: strength and toughness is much higher than cast iron, can be used for wharves, airports and other large span and heavy load environment;
(4) large mesh with the best drainage: water leakage area of 83.3%, more than twice that of cast iron;
(5) beautiful appearance: simple lines, silver appearance, modern idea, saving investment with materials: large span, heavy load, lower than the price of cast iron;
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.
