Special shaped steel grating is also called special steel grating. Make special-shaped, such as: shutter steel grating, diamond hole plug-in steel grating, fish scale hole steel grating, etc. Special shaped steel grating is a kind of irregular steel grating with special shape, such as fan-shaped, which is composed of multiple circular, angular missing and trapezoid through cutting, opening, welding, edging and other processes to meet the requirements of customers. Special shaped steel grating is generally made of carbon steel, and its surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grating has the properties of ventilation, daylighting, heat dissipation, anti-skid, explosion-proof and so on.

Special shaped steel grating packaging

The packing of special-shaped steel grating is generally in bulk or bundled with packing belt, which is mainly determined according to the situation of customers. If there are not many goods and there is no need to load and unload them with forklift, it is generally more convenient in bulk. On the contrary, there are more goods, and it will be more convenient to use forklift for loading and unloading. In short, for the convenience of customers, it is better to protect the products from damage during transportation.

Surface treatment method of special-shaped steel grating

Hot dip galvanizing, cold galvanizing, electroplating, painting, anti rust oil dipping, plastic dipping, (black chip) no treatment.

Production standard of special-shaped steel grating

China yb4001-1991, Yb / t4001-1998, Yb / T4001 1-2007 standard (China is the new steel grating standard of * * in 2007); In addition, the United States, Britain, Australia and New Zealand also have their own standards, which can also be produced according to British bs4592-1-1995 and American ANSI / NAAMM (mbg531-88). Steel standards shall be in accordance with GB700-88 and gb1220-92.

Application of special-shaped steel grating

Petroleum, chemical industry, port, electric power, transportation, papermaking, medicine, steel, food, municipal administration, real estate, manufacturing and other fields. Characteristics of special-shaped steel grating
