Combined Steel Gratings 

 

 

Combined steel gratings made of the steel grating which has spanning ability and the checkered plate which covers the surface. It can use any type of steel gratings and checkered plates of various thickness.Our improvement over the welding and galvanizing process has made it possible to successfully galvanize steel grating and checkered plate as a whole after welding them by unit, without any deform after galvanization. This has ensured the safety of galvanizing coat from being spoiled.

   

Designed and manufactured with pressure welded steel grating,and widely used in the industrial and civil constructions,such as urban road,square,botanical garden,wharf,airport,parking lot,highway,and industrial engineering.
Product features:
Attractive appearance;:simple outline,silver color,and modern
Optimun water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron
Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free
Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft ,safety, and convenient opening
Saving investment:With large span,the cost is lower than that expenses incase of theft and crushing will be saved
High strength:With strength and toughness far higher than those of cast iron,it can be ued in the environment with targe span and heavy load,such as the wharf and the airport
Many specifications available:The requirements of different environments,loads,spans,sizes and shapes can be satisfied

SFD Brand Steel Bar Gratings are manufactured with the world’s first-class computer-controlled pressure resistance welding machine by electro-forging the twisted square-steel into flat steel.The bearing bars (flat steel), running in one direction signifying the length of the gratings, are spaced by rigid attachment to cross rods(square steel) running perpendicular to the bearing bars representing the width.Strong welding points are thus secured.

 

FSD Brand Steel Bar Gratings are classified into two styles,namely plain style,serrated and I style as per the upper edges of bearing bars .More than 200 varieties are available based on specifications and spacing of bearing bars ,and that of cross roda.Different protective treatment can be made on the surface as environment varies.

 

advantages of steel grating
-light weight –easy to install and clean
-modem –nice appearance
-high strength –ventilation and light can pass through
-material saving –slip-resistant&safe
-heavy loading –durable

Grating is widely used in: Power plants, chemical plants, oil refineries, steel mills, paper mills, machinery plants, cement plants, municipal works, sewage treatment, the pharmaceutical industry, food processing and so on.
