Composite Machining for the Construction & Infrastructure Industry

The construction industry builds and maintains the infrastructure the modern world runs on—from power substations and electrical distribution to bridges, water systems, and commercial structures. Projects in this sector demand materials that are strong, lightweight, corrosion-resistant, non-conductive, and able to perform in the field for decades. That’s where thermoset composites from Atlas Fibre make a difference.

Atlas Fibre offers North America’s largest inventory of thermoset composite materials and produces precision-machined components for critical construction applications—from non-conductive standoffs, bus supports, and switchgear barriers to structural profiles, corrosion-free reinforcement, and insulating gaskets. We work closely with electrical contractors, utilities, equipment manufacturers, and structural engineers to reduce cost and complexity—delivering reliable, high-performance solutions built to last.

Benefits of Composites in the Oil and Gas Industry

Thermoset composites offer exceptional mechanical strength, excellent dielectric (electrical-insulating) properties, and outstanding resistance to corrosion, moisture, and weather, making them ideal for the demanding, long-service applications found across construction and infrastructure.

The construction industry needs materials that perform under demanding, long-service conditions. Thermoset composites rise to the challenge thanks to their versatility, durability, and electrical-insulating properties.

Explore a few benefits of using glass fiber-based composites in the construction industry:

Electrical insulation: Glass epoxy grades such as G10/FR4 are excellent dielectric insulators, ideal for non-conductive standoffs, bus supports, switchgear barriers, and utility components where safety and arc resistance are critical.
Corrosion resistance: Unlike steel and aluminum, composites don’t rust or corrode. They stand up to moisture, de-icing salts, chemicals, and coastal air, delivering decades of low-maintenance service in exposed infrastructure.
Light weight: Thermoset composites weigh far less than metal, cutting labor, crane, and installation costs while reducing structural load and making field handling safer and faster.
Strength: Glass epoxy and other thermoset materials have a high strength-to-weight ratio, making them well suited for load-bearing and structural components.
Weather & UV tolerance: Composites hold their shape and properties through temperature swings, moisture, and sun exposure without warping, rotting, or degrading.
Fatigue resistance: Repeated stress, vibration, and wind loading cause metals to develop microfractures and fatigue. Composite materials resist microfracturing, so they hold up under cyclic loads.
Flexibility: Thermoset composites can be engineered to meet your exact specifications. We work with customers individually to create custom materials.

Types of Composites for the Construction Industry

Thermoset composites form many of the components used across the construction and infrastructure industry, including:

Standoff insulators and bus bar supports
Switchgear barriers and phase panels
Arc chutes and arc barriers
Utility pole cross-arms and braces
Terminal boards and insulating spacers
Cable trays and support brackets
Corrosion-free reinforcing bar (rebar) and dowels
Structural profiles, grating, and walkways
Handrail, ladders, and platforms
Thermal-break shims and standoffs
Insulation gaskets and washers

Custom and In-Stock Materials for the Construction Industry

Need help choosing the right material for your project? As a resource center, Atlas Fibre can help. We’ll work with you to decide which materials deliver the best combination of dielectric strength, mechanical performance, and corrosion resistance—while keeping your project cost-effective. We use machine-ready precision blanks to customize your order to exact specifications.

We’re the leading supplier of thermoset composite laminate in the U.S. We have the largest selection of in-stock materials available. Our Illinois warehouse is 120,000 square feet and holds more than $8 million worth of inventory. We also keep an additional $4 million in raw materials at our partner facilities in Massachusetts and Hyderabad, India.

Non-Conductive Components for Electrical & Utility Construction

Non-Conductive Components for Electrical & Utility Construction

Atlas Fibre is an expert in machining glass epoxy materials—such as G10/FR4, G11, and phenolic grades—into the non-conductive components electrical and utility construction depends on. These materials combine high dielectric strength, arc and track resistance, and flame-retardant performance (FR4) with the mechanical strength to serve as load-bearing insulators.

We produce standoffs, bus supports, switchgear barriers, terminal boards, and cross-arms to tight tolerances, helping contractors and OEMs meet safety and performance requirements on substation, distribution, and switchgear projects.

Corrosion-Free Reinforcement and Structural Components

Corrosion-Free Reinforcement and Structural Components

For infrastructure exposed to moisture, chemicals, and de-icing salts, Atlas Fibre supplies and machines composite materials that never rust. Composite reinforcement, structural profiles, and support components resist corrosion and fatigue where steel would degrade—extending service life and cutting long-term maintenance on bridges, decks, water-treatment plants, and coastal structures.

Our decades of experience machining composite materials—and our vertically integrated, high-volume production—make us the ideal partner for demanding construction and infrastructure programs.

Markets

Atlas Fibre has 100% of the capabilities needed to turn raw material into a finished component, making us a formidable vertically integrated company. A wide array of markets require thermoset composites due to their diverse properties. At Atlas Fibre, we cater to those sectors, providing versatile, high-strength thermoset composites to suit unique applications.
