Custom HRSG Fabrication Built for Urgency

Malco fabricates components for HRSG systems, such as insulated casing and insulated ductwork. From rolling and welding to insulation and final assembly, we deliver heat recovery steam generator components built to spec and delivered on your schedule. Whether for combined cycle or cogeneration, our fabrication capabilities and in-house services give you the fast, flexible, and high-performance execution you need.

Based in Oklahoma with 40 ft under hook and a 20-acre footprint, Malco is structured for responsive, turnkey HRSG builds without waiting on capacity or juggling multiple vendors.

Why Choose Malco for HRSG Fabrication

When power plants need steam, there’s no time for delay. Malco brings full-scope fabrication under one roof, so your HRSG system components are built fast and built right.

• Full in-house fabrication and finishing
• Pressure-rated welding and heavy plate rolling
• Rapid coordination with OEM engineers
• Sandblasting, painting, insulation, and assembly
• U.S.-based facility with responsive service

Our team supports your design or builds from your drawings. Either way, we deliver the HRSG system components, fabricated for performance and packaged for transport.

What We Fabricate for HRSG Systems

Malco supports both bottom-supported and top-supported HRSG designs, delivering fully fabricated assemblies and components tailored to your specs:

• Heat-Tolerant Ductwork: large-diameter rolled assemblies, elbows, transitions
• Structural Frames & Steelwork: support frames, braces, lifting assemblies
• Casing & Shrouds: corrosion-resistant, refractory-ready outer shells
• Insulated Internal Sections: lined, pre-installed insulation for high-temperature zones

We understand HRSGs often include high-heat zones requiring refractory protection, an area where Malco’s anchor manufacturing and ceramic insulation supply give us an unmatched edge.

Every component is engineered around performance in high-heat, high-pressure environments and assembled with tight fabrication tolerances.

Turnkey Fabrication Services In-House

Your HRSG shouldn’t be delayed by third-party services. At Malco, we bring everything in-house:

• Material Processing: Plate cutting, rolling, bending
• Welding & Assembly: ASME-ready, heavy-duty fabrication
• Surface Prep & Coating: Sandblast bays, industrial painting, corrosion protection
• Refractory & Insulation: Internal linings and high-temperature materials
• Wiring & Accessories: Electrical integration and control wiring available

The Malco Advantage: Malco doesn’t just fabricate, we manufacture the refractory hardware, supply the insulation, and complete all blasting, painting, and assembly under one roof. Fewer handoffs. Faster delivery.
