America’s Full-Service Galvanizing Experts

Modern hot-dip galvanizing made for speed, scale, and structural certainty for builders everywhere.

Protection That Stands the Test of Time

We galvanize steel. But what we really protect is progress.

At Shannon Galvanizing, we pride ourselves on doing more than coating metal from the elements. We help ensure that America’s infrastructure and roads, its data centers and its energy corridors, endure for decades, safeguarding our friends and neighbors, their families and their investments.

 

What We Do

Full-Service Hot-Dip Galvanizing

Dipping steel or iron parts in molten zinc heated to over 800 degrees grants them decades of corrosion resistance in even the harshest coastal or industrial environments. We hot-dip galvanize to ASTM A123 and QC every piece both visually and structurally.

Project-Scale Galvanizing

Shannon is ready to handle your largest infrastructure projects–whether highways, data centers, energy hubs, or coastal work–while coordinating with multiple fabricators at once. Industry-leading general contractors know and trust Shannon for beating deadlines and meeting all required specifications.

OEM & Niche Galvanizing

We deeply appreciate and provide dedicated support for our serial production customers and OEM parts manufacturers. This includes businesses in industries such as:

  • agriculture (e.g. livestock enclosures and feeders, grain bins and silos, machinery frames)

  • renewable energy (e.g. solar panel supports, electrical cable trays, battery enclosure frames)

  • specialty manufacturing (e.g. conveyor supports and bins, custom steel enclosures, specialty fasteners).

Value-Add Services

Whether you need more or less than our galvanizing services, Shannon has you covered. Other ways we can assist your operations include:

  • abrasion blasting for paint/powder coating prep, weld prep, surface cleaning, or cosmetic finishing

  • metalizing for in-the-field retrofits or large assemblies

  • holes drilled and/or plugged

  • specification guidance (ASTM, TxDOT, LCRA)

  • packaging, trucking, and logistics

  • documentation for accountability and regulatory traceability.

Why Shannon is the Best Choice


We Meet Specs — And Catch What Others Miss

Beyond ASTM A123, we are experienced in galvanizing to other regulatory requirements, including TxDOT and LCRA. When steel arrives with potential issues — such as fabrication errors or incompatible coatings — or when there are customer-specified exceptions or logistical constraints, we use variance forms to prevent rework and preserve the audit trail.

It’s our attention to detail that’s made us a trusted vendor for spec-heavy projects like coastal infrastructure, data centers, and LNG facilities. Consistently delivering premium-quality work keeps our customers coming back again and again.  


We Don’t Just Galvanize — We Respond

At Shannon, we don’t disappear once the steel leaves our yard. We’re available 24/7 to answer questions, adjust schedules, or solve unexpected issues.  And because we inspect early and often — using variance forms to flag concerns before they become problems — we help projects stay on track from the start.


Not a Corporation. Not a Mom & Pop. Just Right.

Shannon Galvanizing is a family-owned business hard at work in the sweet spot between the corporate giants and the small firms. We have the capabilities and professionalism of a much larger operator but the attentiveness of your friendly neighborhood metal shop.
