High-Strength Steel Structure Pig Farm Solution

Core Advantage

Why are modern pig farms around the world turning to steel structures?

Disruptive Advantages Compared to Traditional Structures

Comparison Criteria	Our Steel-Structure Pig Farms	Traditional Brick-and-Concrete / Simple Pig Sheds
Construction Cycle & Cost	Over 60% faster. Components are prefabricated in the factory and assembled on-site; operations can commence within 3–6 months, ensuring a rapid return on investment.	Slow construction (6–12 months or more); heavily influenced by weather conditions and labor availability, resulting in a prolonged capital tie-up period.
Service Life & Maintenance	≥ 25 years. The main structure undergoes anti-corrosion treatment, rendering it rust-proof and corrosion-resistant, requiring virtually no maintenance throughout its service life.	Susceptible to corrosion from ammonia gas and damage from moisture; requires major repairs every 5–8 years, resulting in high maintenance costs.
Biosecurity & Disease Control	Exceptional. Walls feature smooth, seamless surfaces that allow for thorough washing and disinfection, eliminating environments conducive to parasite breeding and significantly reducing the risk of cross-infection.	Walls and floors contain numerous crevices, making thorough cleaning and disinfection difficult; they serve as natural breeding grounds for pathogens.
Environmental Control Capabilities	Precise and efficient. Perfectly compatible with automated ventilation, evaporative cooling systems, underfloor heating, centralized feeding systems, and other technologies, ensuring stable production year-round.	Poor thermal insulation and heat retention; uneven ventilation leads to significant environmental fluctuations, severely compromising pig health and growth efficiency.
Flexibility and Scalability	Modular design allows for easy horizontal or vertical expansion in the future, as needed, to meet evolving operational requirements.	Expansion is virtually impossible; demolition and complete reconstruction entail prohibitive costs.
Return on Investment	Although the initial investment may be slightly higher, the overall return on investment is far superior to that of traditional pig barns, thanks to lower mortality rates, higher daily weight gain, and reduced costs for feed and labor.	High hidden costs—including high mortality rates, low operational efficiency, and substantial maintenance expenses—severely erode long-term profitability.

Diversified pigsty design, covering the entire breeding chain

We provide specialized and refined pigsty design solutions for pigs at different growth stages.

1. Classified by breeding stage and function

● Breeding and Pregnancy House: Adopting a limit fence or intelligent large group feeding mode, the structural design fully integrates welfare facilities such as precise feeding and drinking water systems for sows, and anti slip floors, creating a quiet and controllable breeding environment for sows.

● Delivery room: using core temperature zoning control. Design an independent local environmental control system for the sow and piglet insulation areas, integrating professional facilities such as high beds, insulation lights, and piglet protection pens, which can significantly improve piglet survival rates.

● Nursery: A "kindergarten" for weaned piglets. Here, strict insulation and air quality control are emphasized, using fully or semi leaky flooring, combined with underfloor heating system, to help piglets smoothly pass the weaning stress period.

● Fattening house: with the core goal of improving growth efficiency and cost control. Adopting a large space design, it is compatible with automated feeding and drinking systems, as well as efficient mechanical manure cleaning systems such as scraper plates and fermentation beds, in order to achieve efficient fattening.

● Boar stations and isolation facilities: emphasizing absolute isolation for biological safety. Usually designed as independent units, equipped with independent access channels and strict ventilation and filtration systems to prevent the spread of diseases.

2. Classify by environmental control mode

● The enclosed environment control pigsty adopts a fully enclosed structure, equipped with advanced systems such as negative pressure longitudinal ventilation, wet curtain cooling, and trench ventilation, which can accurately regulate temperature, humidity, and harmful gas concentrations such as ammonia and hydrogen sulfide, effectively isolate external climate interference, and are suitable for large-scale intensive breeding.

● Semi open/naturally ventilated pigsty: With the combination of side wall roller blinds and ridge ventilators, combined with natural and mechanical ventilation methods, it has low energy consumption and is suitable for mild climate areas or cost sensitive small and medium-sized farms.

● Fermentation bed breeding pigsty: a large-span, high eave structure designed specifically for fermentation bed technology, which can provide sufficient space to accommodate bedding and facilitate the installation of rake equipment, thereby achieving zero discharge of manure.

Scientifically Planning Your Pig Farm: Key Decision Elements

1. Determine the core process and column layout

● Feeding mode: adopt "all in, all out" or continuous production? This determines the unit division and cleaning and disinfection process of the pigsty.

● Fence design: The specifications and arrangement of limit pens, delivery pens, nursing beds, and fattening pens directly affect the span, length, and internal passage design of the pigsty.

● Fecal cleaning method: Should we use a fully leaky floor with a scraper, a semi leaky floor with water soaked manure, or a fermentation bed? This determines the depth, slope, and load-bearing and anti-corrosion requirements of the underground manure ditch.

2. Design a matching environmental control system

● Ventilation system: It is necessary to calculate the minimum and maximum ventilation volume required for the pig herd. Negative pressure vertical ventilation is currently the mainstream method, and the number of fans, wet curtain area, and air inlet position should be accurately calculated to ensure uniform air distribution and no dead corners in the building.

● Insulation and cooling: In northern regions, the focus is on polyurethane sandwich panel insulation for walls/roofs (recommended to be over 100mm thick) and underfloor heating systems; The wet curtain fan cooling system and spray cooling in summer are mainly designed in southern China.

● Automatic feeding and drinking water system: It is necessary to plan the direction of the feeding line, water pipes, and installation support points in advance to ensure that each column can conveniently and evenly obtain feed and drinking water.

3. Choose suitable structures and materials

Suggested span

● Single row pigsty: 8-10 meters

● Double row pigsty: 12-16 meters (most economical and efficient)

● Multi column large span: 18-24 meters (suitable for large-scale integrated pig pens)

Key materials:

● Structural anti-corrosion: All steel structures must be treated with hot-dip galvanizing (≥ 275g/㎡) to resist the corrosion of high concentration ammonia gas in the pigsty.

● Roof/Wall: It is recommended to use 50/100mm polyurethane sandwich panels, which have excellent insulation, heat insulation, and moisture resistance properties.

● Ground treatment: It is recommended to use epoxy resin wear-resistant flooring or high-performance concrete flooring to ensure corrosion resistance, slip resistance, and easy flushing.

Our technical strength and quality assurance

● Main structure: The main steel frame is made of Q345B high-strength steel, and the purlins are made of high-strength galvanized C/Z steel, ensuring absolute safety of the structure in harsh weather conditions.

● Professional anti-corrosion: Based on the characteristics of the pigsty environment, we offer two protection solutions - heavy galvanizing (zinc layer thickness ≥ 275g/㎡) or "galvanizing+special anti-corrosion paint" dual protection, which can effectively resist ammonia corrosion and significantly extend the service life of equipment.

● Air tightness design: Professional board seam overlap design and sealing technology ensure good air tightness in the pigsty, which is a prerequisite for achieving precise negative pressure ventilation and energy conservation and emission reduction.

● Load safety: The structural design can be customized according to the wind and snow load standards that occur once every 50 years in your location to ensure safety and security.
