We offer several types of material to suit every budget and project: For deck frames: Steel: a much stronger, more versatile and longer-lasting material which provides an even surface for mounting your decking boards. Pressure-treated wood: the standard budget option. The cut ends are specially sealed to protect against moisture damage. For finish materials: PVC: benefits include superior mould and moisture resistance, coolness to the touch in hot weather, low maintenance, and longevity (with a warranty of up to 50 years). Composite: fabricated from a mix of wood fibres and recycled plastic, composite decking is low maintenance, very durable (covered by a 25-year average warranty) and available in three tiers of pricing. At Delta Decks we are certified installers of the leading composite decking brands – TimberTech/Azek, Deckorators, and Fiberon. Cedar: an attractive alternative to traditional pressure-treated wood decks. Naturally moisture and rot resistant, but we recommend maintenance with a water repellent and UV-protective sealer. Pressure-treated lumber: pine wood which has been treated with a copper pressed solution. Standard entry-level material and prone to splitting, warping and cracking. Should be maintained with water repellent and UV-protective sealer.
