First, from the appearance to distinguish the quality of steel grid plate, can be from the following aspects:

1. Whether the grid is regular, generally rectangular;

2. The welding spot is completely welded and firm. If it is hand-welded steel grilles especially need attention.

3. Whether the cutting margin of the twisted square steel with edge compression welding can be parallel to the flat steel with edge cladding.

4, zinc slag, welding slag treatment is clean.

Second, then is the request factory production of steel grid plate weight is how much? Many customers in the purchase of inquiry when the one-sided pursuit of only steel grid price. Of course, everyone wants the best quality products at the cheapest prices. But there are also a lot of people into the steel grid procurement errors. Cheap steel

Grid plate products are generally because the thickness of the flat steel error is very large. General procurement, the thickness of steel grid plate flat steel is 5mm. But some manufacturers make steel grilles that are only 4.6 mm, and even worse, 4.2 mm, where you can see the size tolerance of steel grilles. For such a relatively high load power requirements of the occasion, there will be safety risks.

Three, the steel grid plate is also known as the steel grid plate, grid plate, steel grid plate is a flat steel in accordance with a certain distance and crossbar arrangement, and welding into the middle with a square grid of steel products. The steel grid plate is mainly used to do gutter cover plate, steel structure platform track plate, steel ladder step plate and so on. The crossbar is generally made of square steel twisted. Steel grid plate is generally made of carbon steel, the appearance of hot galvanized treatment, can play a role in preventing oxidation. It can also be made of stainless steel. Steel grid board with ventilation, lighting, heat dissipation, anti - skid, explosion - proof performance.

Iv. The customer receives the products of the steel grille manufacturer, but also carefully reads the manufacturer's certificate of high-quality steel grille. Here, if it is the regular manufacturers of steel grid, product specifications must be marked by the use of materials, steel grid specifications, product appearance treatment and so on. To sum up, different quality reasons must have different steel grid plate production process, the above is the most simple way to distinguish the quality of steel grid plate.

We will, as always, provide our customers with more exquisite products and higher quality services, together to create a beautiful future and strive to forge ahead!
