Guide

Choosing materials for your build

How to pick between materials for strength, weight, weather and cost.

Know the job

Load, weather, water, heat and wear decide the material more than looks do.

Weight versus strength

Aluminum is light and doesn't rust; steel is cheaper and stronger for its cost; wood is easy to work and repair.

Outdoors and water

Use rated outdoor and marine materials: treated lumber, stainless or galvanized fasteners, sealed electrics.

Cost over its life

A cheaper material that needs replacing sooner can cost more. Ask the draft to compare.

Ask for options

Ask your draft for "a cheaper version" or "a lighter version" to see how materials change the budget.

Concept drafts are for planning, budgeting and talking to professionals. They are not engineering or build plans. Have a qualified professional check any design before you build or use it.
