FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The Johns Creek Owner’s Guide

FAAC welding and fabrication repair in Johns Creek typically runs $340-$780 for most residential swing and slide gate brackets, hinge plates, and operator mounting assemblies, with same-day service when the part is in stock on our truck. We carry FAAC-compatible steel and aluminum fabrication for the 400, 402, 422, and S800 series operators, plus custom hinge and bracket work for older Italian-manufactured units that are no longer supported with OEM hardware. Most owners discover the problem when the gate starts sagging on one side, the operator arm pulls away from the post, or they notice fresh rust streaks bleeding from a cracked weld at the bracket.

Which FAAC Models This Applies To

FAAC has manufactured operators in Italy since 1965, and the hardware standards differ from American brands in measurable ways. The bolt patterns on FAAC 400 and 402 hydraulic swing-gate arms use M10 and M12 metric fasteners with 40 mm center spacing, not the 1.5-inch UNC pattern common on LiftMaster or Mighty Mule brackets. If you are matching a replacement plate, measure the bolt spacing with a metric tape; an imperial conversion will leave you 1.6 mm short and a loose arm that wallows out the holes within two seasons.

The 422 electro-mechanical series and S800 underground operators use heavier-gauge steel for their mounting assemblies, typically 8 mm to 10 mm plate, because the torque load is concentrated at a single pivot point. We stock 8 mm, 10 mm, and 12 mm hot-rolled plate in FAAC-compatible patterns, cut on a plasma table and MIG-welded with ER70S-6 wire for strength match. For operators manufactured before 2010, the OEM bracket may be unobtainable; we fabricate from dimensional drawings or the damaged part itself, and we mark the replacement with the FAAC model number and installation date in paint pen so the next technician knows what they are looking at.

Aftermarket brackets exist for common FAAC models, but we have seen two compatibility failures worth naming. Some imported plates use SAE-grade 5 hardware instead of the metric 8.8-class bolts FAAC specifies, which strips threads under cyclic load. Others omit the gusset weld at the 90-degree corner, the exact point where Georgia humidity pools behind the paint and rust-through begins. We use OEM-spec hardware and full-penetration gussets on every bracket we fabricate.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate droops or drags at the end of its swing. This usually means the hinge pin weld has cracked at the jamb plate, allowing the gate leaf to settle. In Johns Creek, we see this most often on Nesbit Ferry Road properties where heavy iron gates sit on 4-inch posts; the weld heat-affected zone corrodes from the inside out, and the crack propagates slowly enough that owners adjust the limit switch twice before noticing the metal.
• The operator arm chatters or stalls mid-cycle. When the mounting bracket flexes because of a cracked weld or elongated bolt hole, the arm geometry shifts under load. The FAAC control board reads the increased amperage as an obstruction and stops the motor. We find this on 422 series operators where the rear mount plate has worked loose from repeated thermal cycling.
• Fresh rust streaks run from the bracket or hinge. Rust is not cosmetic on load-bearing steel; it indicates moisture behind the paint film where the weld has cracked and capillary action draws water in. By the time the streak is visible, the cross-section has often reduced by 20 percent or more.
• The bracket bolts loosen repeatedly after tightening. This means the hole has wallowed oval from bracket movement, or the weld at the nut plate has failed and the whole assembly shifts. Retightening without addressing the root cause will oval the hole further and ruin the operator arm alignment.
• A visible crack at any weld corner, even hairline. Fatigue cracks in steel propagate perpendicular to stress; on a gate bracket, that means the heel of the fillet weld at the post plate. If you can catch it with a fingernail, it is through the full thickness and growing.

Replacement Cost & What’s Included

What drives the range: material thickness, whether the existing post is sound enough to weld to, and whether the operator arm needs realignment after the bracket is replaced. We quote every job in writing before any torch is lit, under Haven Standard Clause 1. The price includes the fabricated part, mobile welding setup, corrosion-inhibiting primer, and one year of coverage under our 365-Day Done Right Promise. We do not charge separately for travel within Johns Creek.

If the post itself has rotted at the base, we will name that when we find it, photograph it, and quote the reinforcement separately. No surprise invoice at the end.

DIY or Call Us?

There is a short list of things a homeowner can safely check. Verify the bolt tightness with a metric socket set, look for rust streaks or cracks with a flashlight, and photograph any damage for reference. Do not attempt to weld a loaded gate bracket yourself; the gate must be supported independently, the welds must be full-penetration structural fillets, and the cooling rate must be controlled to prevent brittle heat-affected zones. A failed weld on a 400-pound gate is not a do-over, it is a liability.

We carry a 6,000-pound engine hoist and adjustable gantry on the truck for safe gate support, and we test every weld with dye penetrant when the bracket is critical-load. If your FAAC operator is pulling away from the post or the hinge is cracked, call (678) 394-1765. We will quote the repair in writing, do the work, and leave you a photo log of what was found and what was welded.
