Serrated Steel Grid Plate refers to the bearing pressure welded grating bar spacing is less than 25mm. In addition to its fully equipped with the standard pressure welding steel plate in the form of appearance, has the advantages of easy installation, but also to meet the special occasions or leakage through the object size has strict requirements.

Serrated steel grid plate materials and specifications:

Tooth shape flat (material generally is made of Q235) common type is generally 235253255303305323 to 325403404405 specifications. The difference of tooth flat steel and ordinary steel is steel side uneven teeth marks. Mainly due to skid. We used is slitting flat steel, and steel plate cutting and.

Serrated steel grid plate edge:

(1) by one side is flat serrated welded, besides the characteristics and use of ordinary steel grid plate also has a strong grip, especially suitable for wet and slippery, offshore oil production platform;

(2) by hot dip galvanizing surface treatment, has the very strong anti rust capability, 30 years of maintenance free and free replacement. This product can be used as a drain cover frame are connected by a hinge, anti-theft, safety, convenient opening;

(3) made of high strength steel, the steel plate with high strength: the strength and toughness is much higher than cast iron, can be used for the terminal, airport and other large span and heavy load environment;

(4) large mesh has the best: water leakage drainage area of 83.3%, is two times more than the cast iron;

(5) appearance: concise lines, silvery appearance, modern idea of saving investment, saving material.
