Need a part that doesn’t come off a shelf? Mabutas fabricates custom steel and miscellaneous metals for DuPage County builders, businesses, and homeowners. From a simple bracket to a full frame, we cut, weld, and finish it to your spec, then install it on site if you need. Parts that go outside are usually galvanized after fabrication, and the repair only lasts if you finish by restoring the coating after the weld. A bolted retrofit on existing steel usually starts with a plate, clip or gusset made to fit, and this guide to welded and bolted connections covers when bolting is the better repair. Two repair questions that start from existing steel have their own guides: cutting holes in an existing steel beam and whether a damaged steel bollard is repaired or replaced.
