Metal Structure Serrated Galvanized Steel Grating Platform Middle Carbon
Metal Structure Platform Stair Galvanized Welded Steel Grating
Welded Steel Grating Introduction
The steel grid plate is made of load flat steel and horizontal bar according to a certain distance between longitude and weft, using 200 tons of hydraulic resistance welding automation equipment welding into the original plate, after cutting, opening, packaging and other processes and products required by customers.
Load flat steel spacing: the center distance between two adjacent load flat steel, commonly used 30mm, 40mm two.
Rod spacing: the center spacing of two adjacent bars is usually 50mm, 100mm, two kinds, can be produced according to customer requirements.

(1) T1 step: the load flat steel and transverse bar are arranged according to the distance between longitude and weft, and the general steel grid plate is welded and fixed.
(2) T2 step: the step is arranged by load flat steel and transverse bar according to the distance between longitude and weft, and the two sides are fixed with side plate bolts.
(3) T3 step: the step of load flat steel and cross bar arranged according to the distance between longitude and weft, with different anti-skid front guard plate.
(4) T4 step: the load flat steel and transverse bar are arranged according to the distance between longitude and weft, and the step is fixed with different anti-skid front guard plate and side plate bolt.
Welded Steel Grating Application
it is high strength, light structure: the solid grid pressure welding structure makes it has the characteristics of high load source, light structure, easy to lift and so on;
Beautiful appearance, durable characteristics are a lot of extra points for it.
Galvanized steel grid board is widely used in petrochemical, power plant, water plant, warehouse construction, sewage plant, municipal engineering, sanitation engineering and other fields of the platform, walkway, trestle, ditch cover, manhole cover, ladder, fence, road guardrail.
Welded Steel Grating Advantages:
1: high strength, light structure.
2: strong anti-corrosion ability, durable.
3: beautiful appearance, bright surface.
4: no dirt, no rain and snow, no water, self-cleaning, easy to maintain.
5: ventilation, lighting, heat dissipation, anti-skid, explosion-proof good.
6: easy to install his folding unloading.
Welded Steel Grating Process:
The process design of steel grid plate is to arrange the material according to the geometrical information of the sheet according to the size of the original plate, and the ultimate goal is to make the material cutting plan take into account the maximum utilization rate of the material and higher production efficiency.
The principle of steel grid process collocation mainly has the following aspects:
1, all the full plate size or more than the full plate size of the steel grid are in accordance with the length of the priority collocation, collocation size as little as possible and unified, length range control in 5-7 meters.
2. A small number of narrow plates can be arranged in order of width from large to small or from small to large, and then can be combined together in parallel according to length.
3. When the width overflows, the raw material cross bar is used for edge welding, instead of welding another plate.
4, double rod welding machine each pressure welding 2 bars, can not appear odd circumstances.
5, between the board and the board to retain the sawing size, if not enough need to leave a cross bar.
6, for a set of drawings need to be strictly classified.
If multiple drawings are more than 200 square meters, they need to be matched together. If less than 200 square meters, it can be considered to match them with small size drawings.
7, for the special-shaped steel grid, need to consider decomposition and docking, in order to achieve the most economical material.
8, for flat steel spacing 60 mm plate can be used 30 mm spacing comb clip for raw material production.
Welded Steel Grating installation:
The connection mode of steel grid plate is fixed and installed with buckle connector, which is composed of three parts.
Hot Dip Galvanized Steel Grating 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.
Pre-sale service:
After the customer orders, we will have professional technical personnel to contact with the customer, in order to meet the customer's technical inquiry and production schedule.
Your message must be between 20-3,000 characters!
