Durable Insulated Roof Hot-Dip Galvanized Steel Structure Poultry Housing with Bolted Connection

A steel structure house for broiler, layer or breeder flocks. The frame carries an insulated roof and sealed walls, so the house holds its temperature and the airflow is controlled. Frames are fabricated in our workshop and bolted together on site — no on-site welding.

Roof and wall build-up: high-density glass wool plus PU sandwich panels, with roof sheets and an internal ceiling (AZ150 steel). Insulation does more for a poultry house than anything else. A well-insulated, sealed house holds heat in cold weather and keeps cooling cost down in summer, and it holds the air exchange rate you set for the flock.

Sealed steel doors are fitted on the equipment side, and wall and roof joints are gasketed so the house does not leak air where it should not.

Main columns and rafters: H-section steel — Q355 (S355JR equivalent), hot-dip galvanized or AZM coated.

Secondary framing — purlins, girts, bracing and truss chords: American standard channels to ASTM A6/A6M, C-series. C9×134, for example, is a 9-inch channel weighing 13 lb per foot. Grades such as SM490YB, or ASTM A36 / A572 where the drawings call for them.

If your project is drawn to another system, we also supply W-series beams (US), UB/UC and PFC sections (UK / Australia / New Zealand) and JIS sections (Japan). Tell us the standard and we match it.

Side-wall rolling curtains or vent inlets, roof ridge vents and skylight belts. Inlet and outlet sizes are set by the air exchange the flock needs — the layout changes with bird age, stocking density and the climate at your site. Pre-embedded square tubes are built into the frame so feed and water lines, fans and control panels can be fixed on site.

Panels are removable and fasteners are reachable without dismantling the frame. The yearly checks are simple: frame and fixings, wall and roof seals, gutters and drainage, and a touch-up of coating where it is worn. Galvanized or AZM surfaces matter in a poultry house because ammonia in the air attacks bare steel faster than weather does.

1. Foundation — civil work by the client, strictly to the foundation drawing we supply. Anchor bolts are pre-set after our anchor bolts reach the site.
2. Main structure — prefabricated components delivered, columns erected, beams and purlins bolted, bracing installed and aligned.
3. Enclosure — roof insulation and sheets, wall insulation and cladding, then waterproofing and sealing. Hooks for feed and water lines go in after the ceiling panels are up.

To prepare drawings and a price, send us:

• House dimensions — length × width × eave height in metres
• Layout — cage rows or floor pens, and service aisles
• Flock type and capacity — broiler, layer or breeder, and target bird count
• Location — country, city, and whether the site is near the coast
• Wind and snow loads at the site
• Steel standard — ASTM (A6/A6M channels), EN, GB, or another
• Cladding — panel thickness and color

No drawings? Our engineer drafts the layout from these points. Design is free.

The frame is light, so a full house packs into fewer containers than a concrete or timber building of the same size. Main steel frame loads in 40ft open-top containers; roof and wall panels load in 40ft high-cube containers. Lead time is 30-60 days from approved drawings.
