Production line and factory setup overview
A small project-fabrication line converting purchased galvanized round or oval tubing into complete hoop-house and crop-tunnel frame kits through farm/site survey, structural design, tube receiving, cut-to-length, CNC arc rolling, end swaging or connector drilling, brace and base fabrication, optional film-lock channel forming, trial-bay assembly, coating repair, kit counting and installation documentation.
Recommended lowest-entry line configuration Launch one 6-8 m wide naturally ventilated tunnel kit designed for the target province wind and snow. Buy galvanized tube, then install a servo/CNC nine-wheel arc bender for 10-60 mm tube, cut saw, end swager/drill, brace fixtures and a full-bay assembly pad. Add a dedicated film-lock-channel former only after the channel profile and plastic-film system are approved.
Production process and implementation sequence
- Farm survey and structural design
- Galvanized tube receiving and release
- Cut-to-length and batch coding
- CNC hoop arc rolling
- End swaging, drilling and connector work
- Brace, base and door-frame fabrication
- Complete bay trial assembly
- Kit packing, foundation and installation guide
Products, capacity and market fit
- Protected cultivation can extend Afghan vegetable and nursery seasons.
- Local kit fabrication reduces freight and allows province-specific span and bay length.
- Purchased galvanized tube avoids a tube mill and galvanizing plant.
- Wind, snow, anchoring, ventilation and film attachment determine survival.
- Naturally ventilated hoop-house kit - Span, bay, tube grade/coating, hoops, purlins, braces, anchors, vents and film lock - Vegetable and nursery growers
- Low crop-tunnel kit - Crop width, hoop spacing, tube, anchors and cover attachment - Small farms and season extension
