Multi-span film greenhouses have higher land utilization rate than other greenhouses and are cost-effective. They are multi-span greenhouses covered with film. A complete multi-span film greenhouse mainly consists of hot-dip galvanized steel main frame, greenhouse civil foundation, covering materials, hot-dip galvanized steel outer sunshade frame, internal thermal insulation system, outer sunshade system, cooling system with wet curtain and fan, rolling film window system at top and surrounding, power distribution system, spraying system and drainage system.
Solar greenhouse, short for energy-saving solar greenhouse, also known as warm shed, is composed of gable walls on both sides, enclosure walls, supporting frames and covering materials. It is a unique greenhouse type in northern China without indoor heating. The rear wall absorbs solar energy to store and release heat to maintain a certain indoor temperature for the growth of vegetable crops.
Greenhouse breeding, also called warm shed breeding, is an advanced, mature and applicable technology. It can achieve the same breeding effect as fully enclosed livestock houses with low investment. It can reduce livestock and poultry mortality by 2.7%-13.5%, increase meat and egg yield by 12%-25%, and save more than 11% of feed. It promotes the popularization of improved varieties and new technologies, drives moderate-scale breeding, realizes balanced supply of livestock and poultry products, and serves as an important technology for developing high-yield and high-quality animal husbandry.
Oval tubes have become popular greenhouse frame materials in recent years due to excellent compression resistance. Early oval tubes were processed from round tubes, which limited their application due to fixed round tube specifications. Nowadays, they are directly made of galvanized strip steel with adjustable length to reduce promotion restrictions. Greenhouses with oval steel frames have a span of 10-20 meters, length of 50-120 meters, ridge height of 5.0-6 meters and side height of about 1.5-1.7 meters. The greenhouse is covered with 0.15mm anti-dripping film fixed by film pressing lines. Electric film rollers are installed at roof and bottom vents for ventilation and cooling in summer. The whole greenhouse is covered with rainproof thermal insulation quilts outside, and electric rolling machines are equipped on both sides.
Multi-span Polycarbonate Sheet Greenhouse
It has many advantages such as good light transmission, thermal insulation, light weight, high strength, anti-condensation, impact resistance, flame retardancy, economy and durability. Multi-span polycarbonate sheet greenhouses feature large span, spacious and bright interior, good ventilation and high ornamental value. They provide larger space for indoor equipment and personnel movement and better adaptability for internal layout adjustment. Polycarbonate sheets have good elasticity and can be bent into arcs. Their impact resistance is 250-300 times that of ordinary glass. They will not brittle at -40°C or soften at 125°C, with stable mechanical properties under harsh environments. Greenhouses covered with polycarbonate sheets have attractive appearance and excellent thermal insulation, saving heating energy in winter. Compared with single-layer glass greenhouses, they can save 50% energy and greatly cut winter operating costs.

Greenhouse fittings are a full set of supporting components for the construction and operation & maintenance of various multi-span film greenhouses, solar greenhouses, oval tube greenhouses, multi-span polycarbonate sheet greenhouses and breeding greenhouses. Compatible with main materials such as hot-dip galvanized steel frames, oval steel tube frames, PC polycarbonate sheets and greenhouse films, they perform functions including connection & fixing, ventilation & temperature control, sunshade & thermal insulation, water and fertilizer spraying, power distribution and drainage. They are an indispensable part of the complete greenhouse system. Most fittings are made of hot-dip galvanized steel, aluminum alloy, plastic and stainless steel, featuring rust resistance and weather resistance for long-term outdoor agricultural application.
Core fittings include frame connecting and fixing accessories (suitable for all steel frame greenhouses)
Function: Splice and fix main & secondary arch tubes, oval tubes, upright columns and longitudinal beams to build the overall load-bearing frame
Spring wires & lock channels: Fix the edges of greenhouse films and PC sheets to prevent falling off under wind
Oval tube / round tube clamps, connectors, tees, straight joints and elbows: Steel tube splicing parts
Embedded foundation parts, expansion bolts and base steel plates: Fixing components for greenhouse civil foundations
Film tension wires & film clips: Tighten greenhouse films to resist strong winds
