Why Local Customers Choose Metal Mates
01
Nearly 30 Years in the Hunter
We've been locally owned and operated in Cessnock since 1997, which means our name means something in our community. Customers know who they're dealing with, not just a call centre interstate.
02
Everything Under One Roof
From steel bars and RHS to fencing, roofing, aluminium, welding supplies and custom sheds, we stock the lot. One trip to Metal Mates usually beats chasing five suppliers around town.
03
Staff Who Actually Know Their Steel
Our team answers the phone, tracks down what you need and never says "can't help you." Customers keep telling us it's the knowledgeable service that brings them back every time.
04
Competitive Pricing, No Fuss
We price to compete with the big warehouses, without the runaround. Customers regularly tell us they found better quality for less here than anywhere else they checked around the region.
05
Cutting and Fabrication On Site
Need steel cut to size or fabricated for the job? We handle it onsite, so you're not waiting on an outside contractor or paying extra to get material job-ready quickly.
06
Reliable Delivery Across the Hunter Region
We deliver across Cessnock, Newcastle, the Central Coast, Maitland and beyond, so your materials turn up on time. No more juggling pickups around a job that's already running to schedule.

Retain It Posts for Timber Sleeper Retaining Walls
Retain It posts are galvanised steel posts designed to build robust retaining walls from timber sleepers, and Metal Mates stocks them for Cessnock and Hunter Valley landscaping projects of every scale. They're engineered for wall heights of up to 800mm, which covers most residential retaining wall, garden bed and sandpit builds without needing a heavier engineered solution.
- Built for wall heights up to 800mm high
- Suited to building retaining walls, garden beds, sandpits and playgrounds
- Designed to pair with standard timber sleepers, commonly 50mm or 75mm thick
- Galvanised steel construction for long-term corrosion resistance in ground contact
Link Edge Aluminium Garden Edging
Link Edge is a patented aluminium edging product ideal for shaping your next Cessnock landscaping project, and Metal Mates keeps it in stock for both straight-line and curved garden designs. Because it's aluminium rather than timber or plastic, it won't rot, warp or need ongoing treatment, and it pushes straight into the ground without specialist tools, making it a genuinely DIY-friendly product as well as a trade favourite.
- Forms perfect straight lines or smooth curves for garden beds and pathways
- Available in 3 metre lengths, in a width of either 75mm or 100mm
- Rust-resistant aluminium construction that outlasts timber or plastic edging
- Simple push-into-ground installation with no specialist tools required
- Suited to separating lawn from garden beds, paths, pebbles and mulch
SHAPESCAPER Steel Garden Edging Systems
SHAPESCAPER is a modular steel landscaping system built to last, and Metal Mates stocks it for Cessnock customers upgrading garden borders, raised planter boxes or multi-level terracing. Whether you're creating sleek garden edges or a full terraced landscape, SHAPESCAPER makes it straightforward to turn the design into something built on site.
Crafted from durable Australian Bluescope steel, SHAPESCAPER is available in a weather-resistant rusted REDCOR finish as well as Galvabond and Corten options, suited to both residential and commercial projects. Unlike timber or plastic edging, it won't warp, rot or fade, and it's fully recyclable, low maintenance and backed by a 10 year structural warranty.
- Height options from 75mm through to 590mm to suit different edging and terracing needs
- Steel thickness options of 1.6mm, 2.0mm and 2.5mm depending on the application
- Pre-drilled components for quick, straightforward assembly with common tools

Why Choose Metal Mates for Landscape Supplies
Metal Mates has been a locally owned Newcastle supplier since 1997, stocking the retaining wall, edging and garden building products that hold up to real use, not just display models. We carry Retain It posts, Link Edge aluminium edging and SHAPESCAPER steel systems side by side, so our team can compare options honestly rather than pushing a single product line. We supply residential, rural, commercial and industrial customers alike, and you're welcome to visit our Cessnock warehouse to see the full range in person, or call ahead and we'll have your order ready to go.

How It Works
Ordering steel products from Metal Mates for your Newcastle project is straightforward, and we've kept the process simple so you spend less time chasing materials and more time on the job.
Step 01
Consultation and Quote
Getting a quote from Metal Mates starts with a conversation, by phone, email or in person at our yard.

Order Processing and Preparation
Once you confirm your order, Metal Mates pull the stock, cut it to size where needed, and check it over before it goes out the door.

FAQ’s about Landscape Supply in Newcastle
What is the best edging for garden beds and pathways?
For most Cessnock gardens, aluminium edging like Link Edge holds its shape without rotting or warping, and it's easy to install without specialist tools. For a heavier-duty or more architectural look, SHAPESCAPER's steel edging suits raised planters and multi-level terracing. Metal Mates can talk through your site and design to recommend the right product.
How much do landscape supplies cost in Cessnock?
Cost depends on the product and quantity, since aluminium edging, steel edging systems and retaining wall posts all price differently, and project size changes how much you need. Most of what Metal Mates stocks, including Link Edge and Retain It posts, is designed for straightforward DIY installation, which keeps overall project cost down. Our team gives Cessnock customers a clear price and quantity guide before you buy.
How high can a retaining wall be built with Retain It posts?
Retain It galvanised posts are engineered for timber sleeper retaining walls up to 800mm high, which covers the large majority of residential retaining wall, garden bed and sandpit projects. For taller or more heavily loaded walls, our team can advise on the right approach for your Cessnock site.
Does SHAPESCAPER rust or need maintenance?
SHAPESCAPER is made from Australian Bluescope steel and is available in a rusted REDCOR finish that's designed to weather naturally without structural degradation, as well as Galvabond and Corten options. It's low maintenance, fully recyclable and backed by a 10 year structural warranty, so it holds up with far less upkeep than timber or plastic edging.
Can Link Edge be used for curved garden beds?
Yes, Link Edge is specifically designed to form both perfect straight lines and smooth curves, which makes it a popular choice for Cessnock gardens with circular beds, tree rings or flowing borders. It comes in 3 metre lengths in 75mm or 100mm widths to suit different edging depths.
