Silvertop Ash Decking

Starting From Just $7.95

Silvertop Ash is a locally grown hardwood that’s well-suited to outdoor decking in Australian conditions. It’s strong enough to last, without being difficult to handle on-site. With a Janka rating of roughly 7.0 kN and a BAL 19 bushfire rating, it hits the mark for durability, safety, and practicality. At Greenhill Timbers, we stock Silvertop Ash Timber Decking in both 86×19 and 135×19 sizes, and we’re known for offering some of the best prices on hardwood decking across Melbourne and beyond. If you’re after a timber that’s reliable, consistent in look, and won’t blow out the budget, this one’s worth considering.

Product Description

Why Choose Silvertop Ash Decking?

Silvertop Ash isn’t a flash timber, and that’s part of its appeal. It has a straight grain with light blonde to soft brown tones, giving it a clean, low-key finish. It blends in well with both older homes and newer builds, especially when the goal is to keep the look simple.

It tends to grey off nicely if left to weather, or you can apply oil or stain if you want a richer tone. Either way, it stays stable in the long run. Unlike some imported hardwoods, it doesn’t cup or split easily if installed and maintained correctly.

Built to Cope With the Outdoors

This timber holds up well in the weather. It’s rated as Class 2 for above-ground durability, which means it can last a couple of decades or more in outdoor use with normal upkeep. It also has natural resistance to termites, something you want in a deck that’s going to be exposed year-round.

Silvertop Ash Timber Decking also ticks the box for BAL 19 compliance, making it suitable for builds in areas with a moderate bushfire risk. It’s not the highest-rated fire timber out there, but for many suburban and regional builds, it’s a solid fit.

Size Options for Your Diverse Needs: 86 x 19, 135 x 19

One of the things that makes Silvertop Ash so widely used is that it’s easy to work with. It machines well, takes fixings cleanly, and holds its shape once it’s down. Pre-drilling is always a good idea, especially near board ends, but you won’t be fighting with it like you might with denser timbers.

We supply two standard decking sizes at Greenhill Timbers:

  • Silvertop Ash 86×19 Decking
  • Silvertop Ash 135×19 Decking

Each board is kiln-dried, end-matched, and ready for installation. Whether you’re covering a large entertaining area or patching in a section of an older deck, the sizing is flexible enough to suit.

Janka Rating

What Is the Janka Rating?

The Janka rating is a way to measure how hard a timber is, specifically, how much force it takes to push a small steel ball halfway into the wood. The number you get is shown in kilonewtons (kN). A higher Janka score means a harder, more durable timber. Builders and floor installers use it to work out which timbers hold up better in busy areas.

Here’s a rough guide to how some timbers sit on the scale:

  • Brazilian Walnut – around 16.0 kN
  • Spotted Gum – roughly 11.0 kN
  • Tasmanian Oak – about 5.5 kN
  • Radiata Pine – close to 3.0 kN

Keep in mind: these values can vary depending on moisture content and grain direction.

It's One Part of the Decision

Hardness is useful to know, but it’s just one factor. Janka doesn’t tell you how a timber reacts to heat or humidity, how stable it is, or how easy it is to cut and install.

Some of the hardest woods can be difficult to work with. Others, even if softer, might be more stable or forgiving on-site.

At Greenhill Timbers, we look at the whole picture, not just the numbers. All our timbers are structurally graded and covered by a 25-year guarantee. We'll help you pick something that works for your project, not just on paper.
