Frequently Asked Questions (FAQs)

What Is the Basic Structure of a Greenhouse?

A typical simple structure greenhouse consists of:

• Rafters (A): Form the arched roof framework.
• Side Posts (C): Vertical supports along the length of the building.
• Purlins (E): Horizontal beams connecting rafters for added stability.
• End Walls (B) & Side Walls (D): Enclose the structure, often fitted with doors and ventilation systems.

The frame is usually made of galvanized steel and covered with polycarbonate panels or multi-layer polyethylene film to optimize light transmission and insulation.

Is It Cheaper to Buy or Build a Greenhouse?

Purchasing from professional manufacturers is generally more cost-effective than DIY construction. Suppliers benefit from bulk material purchasing, precision cutting, and pre-engineered designs that minimize waste and errors.
