Product Description

Low cost greenhouse, film greenhouse, tunnel greenhouse

Its main feature is simple structure and flexible form.

(1) Simple structure Due to the characteristics of the covering material, the load-bearing structure, solid film system and installation requirements of the plastic greenhouse are relatively simple. Its bearing structure is made of hot-dip galvanized light steel or ordinary steel structure, and the bearing system without purlin system is generally adopted. The longitudinal rods are used as tie rods and connecting beams, which greatly simplifies the structure and reduces the amount of steel used. When the greenhouse adopts the covering material and the roof is not mechanically connected, the roof only bears the gravity load and positive wind pressure, and the wind pressure is transferred to the gutter and the column, which greatly optimizes the stress of the greenhouse structure. The solid film system of plastic greenhouse adopts two ways: fixed and detachable pressing. Fixed material can be anticorrosive wood strip, galvanized steel strip, aluminum alloy strip, etc. Detachable compacting solid film system is also known as "card slot ", card slot is composed of steel, aluminum alloy,PVC and other organic materials, according to the strength of the covering material, life, load bearing conditions, using different forms of card slot. With the development of industrial and greenhouse design technology, a product called "composite card slot" has gradually appeared. This kind of card slot organically combines structural parts with solid film parts, which can be used as load-bearing components and has the characteristics of solid film. At the same time, due to the solid film parts and component production as a whole, but also greatly improve the section characteristics of the component, improve the stiffness of the component and the ability to bear load, performance far component and slot separation structure, in the greenhouse specifications are more standardized, this will become a new technology characteristics and development direction.

(2) Flexible and diverse structure Due to the structural characteristics of plastic greenhouse, coupled with the development process of large plastic greenhouse, affected by regional, customer demand and other factors, all countries in the world are based on their own standards for the production and promotion of plastic greenhouse. Therefore, a large number of different forms, different specifications of plastic greenhouse products, such as different span, height and roof shape of the round vaulted greenhouse, double round arch pointed roof greenhouse, sawtooth greenhouse, small round arch multi-roof greenhouse, etc
