Madden Bolt serves nine core industries, LNG, infrastructure, oil & gas, construction, telecommunications, data centers, transportation, power generation, and petrochemical. Each one gets custom anchor bolts, steel embeds, threaded rebar anchor cages, and fabricated steel, hot-dip galvanized on the same property in our Houston shop. AISC certified, family-owned since 1988, shipping nationwide, and fast on lead times.
Every sector on this list needs the same thing in the end: structural steel that anchors to concrete and holds up for decades in the field. That’s the work we’ve done for more than 38 years. We supply anchor bolts, steel embeds, threaded rebar anchor cages, and custom carbon-steel fabrication to each one below, fabricated, threaded, and hot-dip galvanized in our Houston shop, Texas, then shipped nationwide.
The products overlap across sectors, but the specifications do not. An LNG turbine foundation, a transmission pole base, and a hyperscale generator skid each call for different grades, finishes, embedment shapes, and traceability. Choose your industry below to see how we anchor it.
The common thread across every sector: you deal with one supplier instead of three. Madden Bolt is an AISC certified fabricator with six in-house trades, anchor bolt fabrication, steel embeds, threaded rebar and anchor cages, custom fabrication, plate cutting, and hot-dip galvanizing. The galvanizing kettle has run on the same property as the fab shop since 2007, so parts go from raw steel to finished, coated, traceable product without a single third-party hand-off. That’s what keeps our lead times short.

Madden Bolt supplies anchor bolts, steel embeds, threaded rebar anchor cages, and custom fabrication to nine core sectors: LNG export terminals, infrastructure and transmission, oil and gas, commercial and industrial construction, telecommunications, data centers, transportation, power generation, and petrochemical. We ship nationwide across the United States.
Yes. While our fabrication and galvanizing shop is in Houston, Texas, we ship anchor bolts and fabricated steel nationwide. Our Gulf Coast location keeps us close to LNG, refining, and petrochemical work, but we routinely support construction, power, data center, and infrastructure projects across the country.
Yes, that is the core of what Madden Bolt does. Anchor bolts, steel embeds, threaded rebar anchor cages, and custom fabrication are produced and hot-dip galvanized on the same property in-house, so a single supplier covers the full anchoring package with one QC team and one schedule.
We fabricate anchor bolts to ASTM F1554 Grades 36, 55, and 105, plus A36, A572 Grade 50, A193 B7, A354 Grade BC, A193 B8 and B8M, A320 B8 and B8M, L7 and L43, 1011 and 1018, and 304/316 stainless when a spec requires it. Hot-dip galvanizing follows ASTM A123, A153, F2329, and A767. The right grade and finish are matched to each sector’s loads and exposure.
Pick the sector closest to your structure: LNG and power generation for turbine and generator foundations, infrastructure and transportation for poles, bridges, and signage, oil & gas and petrochemical for refining and process units, construction for buildings and base plates, telecommunications for towers, and data centers for mission-critical facilities. If it spans more than one, send your drawing and we will quote it.
