Repair & mobile welding
Broken weld, cracked joint, bent frame — fixed, not replaced.

Repairs and modifications
Cracked welds, gates knocked off a hinge, railings that have worked loose, fencing damaged in an accident, equipment frames that need reinforcing rather than replacing. We repair metalwork we did not originally build as often as our own — a repair call does not need history with us to get a straight answer about what it will take to fix.
Modifications are the other half of this: adding a reinforcement to something that is flexing more than it should, extending a rail or gate that no longer fits after a remodel, adapting a piece of equipment to a new mount. If the metal is sound enough to build onto, it is usually cheaper than starting over.
Shop repair vs. mobile welding
Anything portable comes to the Hayward shop, where the equipment and working conditions are better and the job usually moves faster. Mobile welding covers what cannot be moved — a gate still on its posts, a railing bolted to a structure, equipment too large or too immobile to trailer in, a trailer itself that is not safe to tow in its current state. We bring a truck-mounted setup to the site for those.
Material matters more than it looks like it should
Steel is the default and what most repairs turn out to be. Cast iron and aluminum both need a different filler and approach, and welding them the wrong way is a common cause of a repair failing again shortly after. If you are not sure what the metal is, a photo often tells us, or we can identify it on site.
How the estimate works
Text a photo of the break or the part that needs modifying. For a mobile call we will also ask roughly where it is and what is around it, since site access affects the job as much as the weld itself.
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.

Repair & mobile welding
What people ask before booking.
What counts as a job for mobile welding vs. bringing it to the shop?
If it can be lifted into a truck and back out again without damage, it usually goes to the shop — better equipment, better working conditions, often faster. If it is attached to a building, a piece of heavy equipment, a trailer that is not roadworthy, or something too large to move, mobile welding comes to you instead. When you call, describe what it is and we will tell you which makes more sense.
Do you repair broken gates, railings and fencing you didn’t originally build?
Yes. A lot of repair calls are for something someone else installed — a gate off its hinge, a railing with a cracked weld, a fence panel that has come loose. We do not need to have built it to fix it.
Can you weld cast iron or aluminum, not just steel?
Steel is the most common material we work with, and the equipment and process are set up for it. Cast iron and aluminum need different filler material and technique and are more prone to cracking if welded the wrong way — tell us the material when you call so we bring the right setup, or say so if you are not sure and we will help identify it.
Is there a minimum job size for mobile welding?
No formal minimum, but a very small repair may cost more delivered as a mobile call than the same fix would at the shop, since a truck roll has its own time cost. If the part is portable, we will usually say so and suggest bringing it in instead — the honest answer, even when it is the smaller invoice.
