Our high-tech production in-house include:

Laser Cutting
(Automated high-bay warehouse)
The following material can be cut: steel up to 25.0 mm, stainless steel up to 20.0 mm (oxide-free), aluminum up to 12.0 mm material thickness.
The max. Machining size is 3000 mm x 1500 mm. All three stocking systems are connected to an automatic high bay warehouse with 220 storage bins (3 tonnes storage capacity). We are thus able to cut during the night shift without staff.
