Special-shaped steel grating is calculated on the basis of large square meters, that is, the large length and width of the special-shaped steel grating are multiplied.
At the time of quotation, if there is no drawing and processed steel grating according to the size specified by the user, the area is the actual number of steel gratings delivered multiplied by the sum of width and length, including openings and cuts. If the customer can provide drawings for the user to design the plane layout of the steel grating, the area is calculated according to the total outer dimensions on the drawing, including the openings and notches. For special-shaped steel gratings, the area is width (W) × length (L), and the cut part is not deducted.
Special-shaped steel grating is a kind of irregular steel grating. It is made up of multiple circular, fan-shaped, and trapezoidal shaped steel grating products that meet customer requirements through cutting, perforating, welding, and edging. The special-shaped steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grille has the properties of ventilation, lighting, heat dissipation, anti-skid, and explosion-proof.
