II. Production

Core Structural Components

Arch frame skeleton: Hot‑dip galvanised round‑steel tubes / oval steel tubes assembled into an arch shape, fitted with upright posts, horizontal tie rods and diagonal braces for wind‑resistance and snow‑load resistance. Anti‑corrosion treatment is applied to the skeleton to resist corrosion caused by ammonia and humid air inside the shed.

Enclosure covering system: PO greenhouse film. High‑grade versions adopt double‑layer film with an intermediate air‑insulation layer. Electric film rollers, thermal‑insulation quilts and sun‑shade nets are installed on the outer side to enable automatic opening and closing of side‑wall film.

Door, window and ventilation components: Insulated main doors and access doors, reserved openings for fans, cooling pads and air vents. The film‑rolling system provides large‑scale side‑wall ventilation.

Internal civil‑engineering works: Cement‑hardened floors; partition fences for floor‑rearing pens; manure‑removal tunnels reserved underneath nets for net‑bed systems; well‑designed internal drainage.

Embedded equipment interfaces: Pre‑reserved openings for feed‑line, water‑line and environmental‑control sensor pipelines to accommodate the installation and connection of automatic equipment.

Production and On‑site Implementation Process

Shed scheme design is carried out according to site conditions, breeding scale and local wind‑snow loads, confirming the span, length and height of the greenhouse‑type poultry house.

Steel tubes are cut, perforated and hot‑dip‑galvanised in‑factory. Standardised accessories are packed and delivered to the site.

On‑site construction: Foundation pouring → assembly and fixation of arch frame skeleton → laying and compaction of greenhouse film → installation of film rollers, thermal‑insulation quilts and door‑window openings → civil‑engineering construction of floors and tunnels.

Final acceptance inspection: Check skeleton stability, greenhouse‑film sealing performance and operation of film‑rolling mechanisms before hand‑over for breeding‑equipment installation.

III. Services

Pre‑project planning: On‑site land survey. Deliver shed design solutions based on breeding species, stocking capacity and local wind‑snow & climatic conditions, and assist with investment estimation.

Production and installation: Factory‑fabricated steel‑tube components, on‑site erection by professional teams, commissioning of film‑rolling and thermal‑insulation systems.

Technical disclosure: Inform breeding‑equipment contractors of opening dimensions and skeleton load‑bearing parameters to ensure compatibility between the building and farming facilities.

After‑sales maintenance: Skeleton reinforcement inspection, greenhouse‑film damage repair and film‑roller maintenance; supply replacement services for wearing parts such as thermal‑insulation quilts and greenhouse films.

Value‑added services: Renovation and upgrading of old sheds with retrofitted fans, cooling pads and electric film‑rolling systems; design of auxiliary buildings; provision of technical documentation required for project acceptance.

IV. Advantages

Low construction cost and small investment pressure: The construction cost for the same floor area is far lower than that of steel‑structure insulated poultry houses. Low upfront investment enables small‑and‑medium‑scale projects to start up quickly.

Short construction cycle: Factory‑prefabricated components and on‑site assembly deliver fast construction, allowing rapid commissioning and payback.

Flexible disassembly and relocation: Modular skeleton permits later‑stage reconstruction and relocation, supporting flexible project adjustments.

Good daylighting conditions: Transparent greenhouse film provides abundant natural light inside the shed, which benefits poultry growth and reduces lighting‑energy consumption.

Flexible ventilation regulation: Electric film rollers enable large‑area side‑wall opening for effective ventilation and heat dissipation during hot seasons. The shed is compatible with a full set of automatic breeding equipment to realise automated feeding, drinking‑water supply, manure removal and environmental control.

High site adaptability: Low foundation requirements make it suitable for irregular‑shaped land parcels, ideal for cooperatives and family‑run farms.

Objective Limitations

Thermal insulation performance is weaker than poultry houses built with steel‑structure sandwich panels, resulting in larger diurnal temperature differences. Greenhouse films and thermal‑insulation quilts are consumables that require replacement every 3‑5 years. There is a risk of structural damage under extreme wind‑snow weather. Limited air‑tightness restricts its use for high‑rise stacked cage‑rearing. Enhanced thermal‑insulation configurations are required for severely cold northern regions.
