Graedstrup Stal has focused entirely on engineering and manufacturing trusses and columns for the steel structures it supplies to Danish construction companies. "We only do the assembly on site, using our own trucks and cranes. We leave the finishing up to the contractor. With a powder coating installation in-house, we are unique, and we can keep an optimal grip on the high quality," explains Allan. Every year the company processes more than 5,000 tons of steel, good for 6 to 7 hall projects a week”.
The construction parts are prepared by the engineers in Tekla® CAD, after which the parts are produced with punching, drilling/sawing and plasma cutting machines. “Due to the large variety of dimensions, we mostly weld manually on 2 welding lines. However, the welding of end and support plates on the steel profiles is monotonous work for the welders, for which we deployed a welding robot some time ago. However, this was limited to serial production. Programming just a few pieces was too time-consuming. For us a reason to look for another system", explains the Production Manager.
