High Yield Structural Steel Plates :
S690 QL is a high yield structural steel grade produced in compliance with EN 10025:6:2004. The material is heats treated using the quench and temper process and has good bending and welding properties.

- The code “S” for steel grade S690QL means structural steel.

- The code “Q” refers to the delivery condition, in this case to quenched & Tempered.

- The code “ L” means that the average minimum values for impact energy have been defined at a temperature
of -40°C.

Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.

The steel is used in a variety of sectors including
- Heavy transportation
- Machine building
Steel constructions
Lifting equipment

Applications : Crane booms, mining and earthmoving equipment, bridges, material handling, trailers and agricultural equipment.
