Production line and factory setup overview
A micro metal-fabrication workshop converting purchased mild-steel bars, hollow sections and decorative elements into measured security grilles and window guards through site measurement, cut-list preparation, sawing, punching, cold bending and scroll forming, jig assembly, MIG welding, grinding, corrosion pretreatment, painting or powder coating, anchor preparation, fit inspection and installation.
Recommended lowest-entry line configuration Begin as a build-to-order workshop with one cold saw, section bender, compact scroll/twist machine, 40-60 t ironworker, two MIG welders, modular fixture tables, grinders and wet-paint booth. Standardize three infill patterns and two frame sections while every opening remains measured. Add powder coating only after throughput supports proper pretreatment and curing.
Production process and implementation sequence
- Site survey and approved drawing
- Steel receiving and cut-list nesting
- Sawing, punching and end preparation
- Cold bending, scroll or twist forming
- Fixture assembly and MIG welding
- Grinding and corrosion pretreatment
- Painting, curing and hardware fit
- Dimensional inspection, packing and installation
Products, capacity and market fit
- Homes and shops routinely need made-to-measure window and entrance protection.
- Afghan workshops can source standard steel sections and use local skilled fabrication labor.
- Build-to-order production limits finished inventory and expensive profile tooling.
- Safe egress, anchor design, weld quality and corrosion protection matter more than ornament.
- Fixed window security grille - Opening, frame, bar spacing, anchor type, weld, finish and emergency-egress decision - Homes, shops and offices
- Hinged or removable guard - Approved hinge, lock, release route, frame clearance and corrosion finish - Locations requiring cleaning or emergency access
