Whether you’re building a new frame, finishing a deck, or supplying materials for a landscaping job, choosing the right timber matters. Our Christchurch timber category covers structural, treated, framing, decking and landscaping timber suited to local conditions in Canterbury.
Timber types and where to use them
Structural timber is used for load-bearing work — think framing studs, rafters and bearers. Framing options range from untreated H1.2 for interior use to higher-treatment grades for exterior applications. Treated timber (H3.2/H4 types) is suited to decks, exterior trim and ground contact areas where moisture and decay resistance are required.
Decking and landscaping
Decking choices include durable hardwoods like Garapa and Kwila, or plantation Radiata options in H3.2 grades. When selecting decking consider timber species, board thickness, and finish. Landscaping timbers (sleepers and posts) often require higher treatment levels to withstand soil contact.
Practical buyer guidance
- For sub-floor and framing: use framing-grade timber sized to your plans; consider H1.2 for interiors and H3.2 or H4 for exposed or ground-contact parts.
- For decking: choose wider, thicker boards for high-traffic areas; hardwoods give longer natural durability but cost and maintenance differ from Radiata options.
- For landscaping: use H4 or similar for sleepers and posts in direct soil contact to reduce decay risk.
- Check board dimensions and edge profiles against plans — standard sizes include common framing and decking dimensions.
