Products Description

 

 

S690QL1 steel plate, better known as SUPRALSIM 690, is an ideal budget steel plate, offering minimum yield strength of 690 MPa. Our S690QL1 structural steel plates are fine-grained for maximum performance in precarious working conditions. Produced in compliance with EN10025:6:2004, these structural steel plates are rampantly applied where high strength and light weight are needed.

Application of our S690QL1 Structural Steel Plates

 

 

• Excavator buckets, an integral part of the mining and road construction business are manufactured using SUPRALSIM 690 structural steel plates, shielding them, either wholly or partially from impact force deriving from the collision with Earth, reducing friction and upkeep time of machinery.

 

• Shovel and Cranes, their booms and their types like tower crane, portable crane, cable crane and truck mounted crane are heavy weight lifters, leading to their production by S690QL1, SUPERELSO 690, EN FeE690VKT, grade steel plates, light in weight and carry the extra load.

 

• Agriculture industry utilises DIN TStE690V, RQT 70, etc. steel plates in machines like tractors, combine harvesters, disc harrows, sprayers, etc. to oppose friction and fissures caused due to constant contact with mud and stones. The supreme hardness of steel surfaces breaks rocks into small parts quickly.

 

• Pressure vessels like fixed and transportable storage tanks, vessels, etc. use RQT 701, NAXTRA 700 structural steel plates because they are malleable smoothly, create slim assemblies, save space and contain constant machining, necessary in powerful systems.
