Agricultural buildings vary by storage, livestock or processing use. Open sides, ventilation, washdown and local exposure can influence the frame layout and protection choice. ZSJH manufactures steel columns, rafters, braces and connections around approved agricultural layouts and protection requirements.
1. Open-side and ventilation design. Frame layout suits open sides, ventilation ridges and natural-vent configurations.
2. Corrosion protection matched to use. Primer/paint or hot-dip galvanizing selected for washdown, livestock and locally exposed environments.
3. Wide-span storage and processing. Clear spans and bay lengths tailored to storage, livestock and processing layouts.
4. Drawings-first fabrication. Produced to approved drawings; structural design, calculations and detailing available on request.
5. Quality control and documentation. Weld details, tolerances and surface protection tracked and documented per project.
6. One-window export service. Packing, marking, shipping documents and delivery scope handled to your destination.
The following are typical options. Actual specifications are subject to approved drawings and project requirements.
| Item | Typical Range | Note |
|---|---|---|
| Component Types | Steel columns, roof beams/rafters, bracing, purlins/wall girts, open-side columns and connection components | Custom-fabricated as a coordinated package to suit the agricultural building layout |
| Common Steel Grades | Q355B (GB/T 1591-2018); ASTM A36 / A572 Gr.50 / A992; EN S275 / S355 | Selected according to project design requirements |
| Plate Thickness | Typically 6–80 mm; heavy components fabricated according to drawings | Subject to approved drawings |
| Welding Standards | AWS D1.1 / ISO 3834 / GB 50661, as specified for the project | Traceable welder qualifications |
| Fabrication Tolerances | ISO 13920 or GB 50205-2020, as specified for the project | Subject to tolerances specified on the drawings |
| Surface Treatment | Blast cleaning to Sa 2½ (ISO 8501-1), followed by primer and topcoat; or hot-dip galvanizing (ISO 1461) | According to environmental conditions and corrosion-protection requirements |
| Individual Component Weight and Dimensions | Determined for each project within fabrication, lifting and transportation limits | Split into transportable sections as required |
| Inspection | Dimensional and weld inspection; nondestructive testing (UT/MT/RT) and third-party inspection as required | According to project specifications |
Typical applications include farm storage buildings, livestock facilities and agricultural processing workshops. Corrosion protection and design loads follow the project specification; no blanket service-life claim is made.

Question | Answer |
Do you fabricate only to drawings, or also provide design? | We fabricate to your drawings and can provide structural design, calculations and detailing, depending on how complete your drawings are. |
How do you handle corrosive livestock or washdown environments? | We select primer/paint or hot-dip galvanizing per the project's exposure and washdown requirements. |
Can the frame suit open sides and ventilation? | Yes — frame layout, ridge vents and open-side posts are detailed to your approved agricultural layout. |
Can you export to our country? | Yes, as break-bulk or container cargo, with documents for destination customs clearance. |
What documents do you provide? | Mill test certificates, inspection records, packing lists and shipping documents; third-party inspection per project. |
Do you guarantee a service life? | No blanket service-life claim is made; corrosion protection and design loads follow the project specification. |
Send ZSJH your project location, drawings or BOM, building use, length/width, span, height, open-side and ventilation details, local exposure, steel sections, coating/galvanizing preference, quantities, inspection scope, delivery destination and target date. If drawings are incomplete, ask about structural design, calculations and detailing support.
