Trellis and pergola structures
A metal trellis built for an actual climbing plant needs to carry real, growing weight over years, not just look right on the day it goes in the ground. We build the frame for the load it will eventually bear, sized and braced for the plant and the span, not a decorative panel scaled up.
Pergola-style structures follow the same logic — a welded steel frame is a different build than a wood kit, with different footing and attachment requirements. We’ll walk the site before finalizing a design.
One-off custom metalwork
Equipment stands and mounts, brackets that need to carry a specific load, structural pieces for a renovation that a contractor has specified, metal furniture or fixtures — anything that starts with “can you build this” and does not fit neatly into railings, gates, fencing or security bars lands here. If you have architect or engineer drawings, we fabricate to spec directly.
No drawing? That's normal, not a problem
Most custom jobs start as a photo of something similar, a rough sketch on paper, or a phone call describing what the piece needs to do. We turn that into something buildable and confirm exact dimensions on site before cutting anything — you do not need CAD drawings to get an honest estimate.
How the estimate works
Send whatever you have — a photo, a sketch, a set of drawings, or just a description — and we’ll ask the questions needed to scope it. For anything structural or site-specific, we’ll confirm measurements in person before quoting a final price.
Supplier catalogs
Colours and components you can look at before you decide.
These are the suppliers whose catalogs get opened on ATR jobs. Read them as a starting point rather than a menu — what is actually right for your piece depends on the design, the exposure and how it gets fabricated, and we will confirm that at the estimate.
Powder coat colour
Powder coat is where nearly every colour decision on a job actually gets made. These are the colour cards ATR works from — pick something you like, bring the code to the estimate, and we will tell you honestly whether it suits the exposure that piece is going to live in.
- Open Essentials colour card
Essentials, Volume 6
The standard range — the colours most jobs land on, in the gloss levels and textures they are actually available in.
- Open Super Durable card
Super Durable, Volume 3
The range worth reading if the piece faces south or west. Super durable powders hold their colour years longer under direct sun than standard polyester.
- Open Metallics card
3D Metallics, Volume 2
Metallic and effect finishes, for when a flat colour is not the look. They read very differently in person than on a screen — treat the card as a shortlist, not a decision.
- Open Cardinal colour card
Powder Coatings Colour Card
A second full colour card, from a West Coast powder manufacturer. Useful as a cross-check when a colour you want is not stocked in the TIGER range.
Cable railing infill
Cable infill keeps a view open where pickets would close it down. It is also the infill people most often get wrong — cable has to be tensioned against a frame stiff enough to take it, or the runs go slack and the spacing opens past code. The hardware references below are what ATR builds to.

Product literature and specs
The wider library — installation detail, technical drawings and spec sheets, if you want to read past the colour and into how it goes together.

Custom fabrication
What people ask before booking.
What if I don’t have a drawing, just an idea?
That is normal. A photo of something similar, a rough sketch, or just a description of what the piece needs to do is usually enough to start. We will ask the questions needed to turn it into something buildable, and for anything structural we will confirm dimensions on site before fabrication.
What kinds of things count as "custom fabrication"?
Anything that does not fit neatly into railings, gates, fencing or security bars — a trellis or pergola frame, a custom bracket or mount, a piece of furniture or fixture in metal, equipment stands, one-off structural pieces for a renovation. If it needs to be welded and it is not on the list of our other services, it likely lands here.
Do you build trellis and pergola structures for plants, not just decoration?
Yes — a metal trellis built to actually carry the weight of a mature climbing vine is a different design problem than a decorative panel, and we build for the load it will eventually carry, not just how it looks on installation day.
Can you fabricate from a design someone else made — an architect or designer?
Yes. If you have drawings from an architect, designer or engineer, we can fabricate to those specifications directly, and will flag anything that looks off from a fabrication standpoint before building it.
