Most of the materials and budget for your project will be barn timber. Your plan should include instructions on the type of timber to use. Most timber sheds are made of pine, the cheapest and most durable cedar, an alternative to the middle class, and redwood, which is the most expensive and strongest. 

The selection should be made based on budget, wear and tear, and aesthetic considerations. Once the type of timber is selected, the purchase of treated timber frame roof at https://heydenframeandtruss.com.au/premade-wall-frames/ is divided into two types: pressure-treated timber and ordinary timber. 

The material you buy depends on whether the timber is in contact with the ground or not. 2×4 plywood and roofing timber that does not touch the floor can be made of plain timber.

The parts of the warehouse that touch the ground are different and must be made of pressure-treated timber. In the manufacture of pressure-treated timber, chemicals are introduced to the timber under vacuum, so that it is resistant to rot. 

Timber that touches the ground is more likely to be exposed to water, termites, mold, bacteria, or damage. Timber impregnated with this chemical is more resistant to these dangers.

Since the timber is saturated with the vacuum process, the edges remain protected even when the timber is cut. The color may vary slightly due to natural oxidation and aging, but rest assured that the timber is always protected.
