FAQ

Frequently asked questions

Briefly about industry tasks, quotes and drawing formats. Other questions — in the FAQ block on the home page.
How are your flue ducts different from ventilation ductwork?
Ventilation ducts are usually made of 0.5–1.5 mm galvanized sheet. Flue ducts and dust extraction at a metallurgical plant carry abrasive dust that wears through such metal quickly. We make flue ducts and air ducts from 1–20 mm plate, not only in carbon steel, with liners on bends.
How do I get a cost estimate and how much does it cost?
The estimate is free. Send your drawing and a description of the task through the form on the site, via WhatsApp or to info@kztm.kz — an engineer will prepare a commercial offer with exact pricing and lead times from 24 hours on business days.
What formats do you accept drawings in?
2D drawings: DWG, DXF, PDF, as well as native CAD formats — IDW (Autodesk Inventor), CDW/FRW/SPW (KOMPAS-3D), SLDDRW (SolidWorks), DRW (CATIA). 3D models: STEP (.step, .stp), IGES (.iges, .igs), Parasolid (.x_t, .x_b), SAT (ACIS), as well as native ones — IPT/IAM (Inventor), SLDPRT/SLDASM (SolidWorks), CATPart/CATProduct (CATIA), m3d/a3d (KOMPAS-3D), PRT (NX, Creo). If you only have a paper sketch or a sample part, our design engineers will prepare the working drawing themselves.
