Madden Bolt runs every steel fabrication trade across our Houston facilities, custom anchor bolts, steel embeds, threaded rebar and anchor cages, bell bottom sleeves, miscellaneous carbon-steel fabrication, high-precision plate cutting, and in-house hot-dip galvanizing. Six trades, one QC team, one purchase order take your part from raw steel to the finished, galvanized product. AISC certified, family-owned since 1988, and fast.
Most steel jobs pass through a handful of vendors, one shop cuts the plate, another welds the assembly, a third threads the rod, and an outside galvanizer coats it. Every hand-off adds freight, schedule risk, and one more party to chase down. We don’t work that way. Our steel fabrication services cover the whole scope in-house: plate cutting, fabrication, threading, assembly, and hot-dip galvanizing run on the same property, under one quality team. That means a single point of accountability and short lead times, which is why structural engineers and EPC procurement teams have come to us since 1988.
Every capability below feeds the others. Order a single product or a complete structural package, it all ships as one source, galvanized and traceable.
Custom anchor bolts are Madden Bolt’s foundation product. We fabricate J-bolts, L-bolts, U-bolts, eye bolts, plate (template) bolts, double-end threaded rods, and continuous all-thread to ASTM F1554 Grades 36, 55, and 105, and to A36, A572 Grade 50, A193 B7, A354 BC, A193 B8 and B8M, A320 B8 and B8M, L7 and L43, 1011 and 1018, and 304/316 stainless when a spec requires it. Diameters run from 3/4 inch to 3 inches, with complete assemblies kitted with heavy hex nuts, washers, and setting templates. Explore anchor bolts.
Steel embeds tie structural steel to concrete. We build concrete embed assemblies, F1554 anchor bolt assemblies, threaded studs, headed concrete anchors, shear connectors, jam nuts, and anchor plates, welded, drilled, and finished to your engineer’s detail, then galvanized in-house on the same property. See our steel embeds and concrete embeds.
We fabricate threaded rebar in #3 through #18J (A615 Gr. 60/80), with threads cut or rolled onto one or both ends, plus dual-thread bars — cut, threaded, and hot-dip galvanized at our Houston rebar facility. Explore threaded rebar.
We assemble, weld, and tag anchor bolt cages in #14J and #18J rebar (A615 Gr. 75) for transmission, foundation, and pole work — built to your drawings and hot-dip galvanized in-house. Explore anchor bolt cages.
Beyond bolts and cages, Madden Bolt is a custom carbon-steel fabricator: brackets, weldments, sole plates, base plates, leveling plates, sleeves, pipe bollards, and structural shapes like angle, beam, channel, pipe, and flatbar, all cut, drilled, welded, and finished in-house. High-precision plate cutting feeds the fabrication line, so plate components and the assemblies that use them come from the same shop, and ship galvanized and traceable.
Corrosion protection is not a separate trip to an outside vendor. Madden Bolt hot-dip galvanizes anchor bolts, embeds, rebar cages, and fabricated steel in-house per ASTM A123 (fabricated steel), A153 (bolts, nuts, washers), F2329, and A767 (rebar). The galvanizing kettle has run alongside the fabrication shop since 2007, which means consistent zinc-coating thickness lot to lot, one QC team from raw steel to finished part, and zero third-party scheduling delays. Learn about in-house galvanizing.
Madden Bolt is an AISC certified fabricator and an AWS CWF (Certified Welding Fabricator) with an on-staff Certified Welding Inspector (CWI). Every order (anchor bolt, embed, cage, or weldment) is fully traceable, backed by mill test reports (MTRs). One quality team signs off on every lot, from material receipt through final galvanizing. See our full quality and safety standards.
Madden Bolt products anchor critical structures across the United States, LNG export terminals, power generation plants, petrochemical and refining units, infrastructure and transmission, data centers, and commercial construction.

Custom anchor bolts, steel embeds and embedded plates, threaded rebar and anchor bolt cages, bell bottom sleeves, and miscellaneous carbon-steel fabrication, plus high-precision plate cutting and in-house hot-dip galvanizing. Six trades across our Houston facilities. A part gets cut, drilled, welded, threaded, and galvanized.
One source, one purchase order, one QC team, from raw steel to the finished, galvanized part. Fabrication, threading, plate cutting, and galvanizing all run on the same property, so nothing gets handed to an outside vendor, nobody waits on someone else’s schedule, and one team owns the result. That’s how we keep lead times short.
Yes. Madden Bolt is an AISC certified fabricator and an AWS CWF (Certified Welding Fabricator), with an on-staff Certified Welding Inspector (CWI). Every order is fully traceable, with mill test reports (MTRs) available on request.
Yes, in-house. Our hot-dip galvanizing kettle has run on the same property as the fabrication shop since 2007, so anchor bolts, embeds, rebar cages, and fabricated steel are galvanized per ASTM A123, A153, F2329, and A767 without leaving for an outside galvanizer. That removes the single biggest source of lead-time delay on most steel orders.
Madden Bolt fabricates in Houston, Texas and ships anchor bolts, embeds, rebar cages, and fabricated steel nationwide across the United States. We routinely support LNG, power generation, petrochemical, infrastructure, data center, and commercial construction projects from coast to coast.
