Seven product families. Every line on the quotation is one of them.

A greenhouse frame is a bill of materials before it is a structure. These are the lines we manufacture, cut, coat and pack: four tube geometries, two cold-formed profile types, roll-formed gutters, and the fittings that turn them into a house.

Buyers usually arrive with one of two documents: a drawing from their house designer, or a list of sections copied from a previous order. Either is enough. What we need in addition is the coating class, the quantity, and whether lengths must be 6 m, 12 m or cut to a specific bay.

How to read a product page

Every size page carries the same four blocks: a dimension and weight table with calculated nominal weights, the jobs that section is usually bought for, the fittings it pairs with, and the packing note for export. Nothing on those pages is a catalogue promise — the mill certificate for your heat is the binding figure.

Section selection belongs to your structural engineer. We quote what is specified and flag when a section looks light for the stated load.
