Merch grade decking is an affordable choice for building decks, patios, boardwalks, and outdoor entertaining areas where value is a priority. WBS Henderson stocks H3.2 treated Radiata Pine merch grade decking in smooth and grip profiles, with a selection of widths and thicknesses to suit a wide range of residential landscaping and decking projects throughout Auckland and New Zealand.

Merch Grade Decking for Cost-Effective Outdoor Projects

Merch grade decking offers a practical and economical solution for homeowners, landscapers, and builders looking to create durable outdoor spaces without the premium price tag. Manufactured from H3.2 treated Radiata Pine, these decking boards are designed for above-ground exterior use and are well suited to decks, walkways, garden features, and other outdoor structures exposed to the New Zealand climate.

What is Merch Grade Decking?

Merch grade decking is treated and manufactured to the same structural and durability standards as premium decking, but it allows for a greater number of natural timber characteristics. Boards may contain more knots, colour variation, grain movement, resin pockets, or other cosmetic imperfections that do not affect their strength or service life.

For many homeowners and builders, these natural features become less noticeable once the deck has weathered or has been stained or coated, making merch grade decking an excellent value-for-money option.

Merch Grade Decking Options

WBS Henderson stocks merch grade decking in smooth and grip profiles, with popular sizes including 100 x 25, 100 x 40, and 150 x 40 (nominal sizes). Boards are supplied in random lengths, helping reduce waste and providing flexibility across a wide range of decking layouts.

Smooth boards provide a clean, contemporary appearance that is comfortable underfoot, while grip profile boards offer additional traction, making them a popular option for steps, sloping sites, and areas that may become wet. All boards are H3.2 treated to provide protection against fungal decay and insect attack in above-ground applications.

Merch Grade vs Premium Decking

The main difference between merch grade and premium decking is appearance rather than performance.

Premium grade decking is selected for a cleaner, more consistent finish with fewer visible knots and blemishes, making it a popular choice for architectural homes and premium outdoor living areas.

Merch grade decking offers the same H3.2 treatment and durability but includes more natural timber variation. It is well suited to family homes, rental properties, renovations, landscaping projects, and larger decks where achieving the best balance between quality and budget is important.

For many projects, merch grade decking delivers the best overall value. It is generally more affordable than premium grade decking because the boards contain more natural visual characteristics rather than differences in strength or durability. On larger decks, choosing merch grade can provide worthwhile savings while still delivering a long-lasting outdoor surface.

Ideal for Residential and Landscaping Projects

Merch grade decking is commonly used for backyard decks, patios, garden paths, seating areas, boardwalks, and outdoor entertaining spaces. It is also suitable for rental property upgrades, renovations, and landscaping projects where balancing appearance, durability, and budget is important.
