FAQ

Company & Manufacturing FAQ

Frequently asked questions and technical answers about demountable steel container frames.

No. Our manufacturing is strictly focused on galvanized steel demountable frames for prefab living cabins, site offices, and residential modular structures. We do not produce heavy ISO ocean cargo containers or heavy vehicle transport trailer chassis.
A demountable container frame kit is a load-bearing steel structure manufactured from roll-formed galvanized steel profiles. Connected completely with bolts and nuts without welding, it can be assembled or disassembled easily for offices, site accommodation, or warehouses.
No welding is required. All profile connections are fastened using galvanized bolts, nuts, and pre-drilled connection plates. Assembly can be completed in 1.5 to 2 hours using standard wrenches.
Yes! The 3x7m demountable frame profile sets are flat-pack bundled so up to 24-26 complete sets fit into a single 40ft High Cube ocean shipping container.
Stock orders (1-5 sets) are dispatched within 3-5 business days. Bulk export orders (10+ sets) require 7-14 business days production time. Ex-factoryGebze delivery terms apply.
