FRP Structural Shapes, Grating & Stair Treads: Which Solution Is Right for Your Facility?

Choosing the right material may not seem critical at first. But over time, corrosion, slippery walking surfaces and repeated maintenance can affect safety, productivity and operating costs throughout a facility.

Fiberglass-reinforced polymer (FRP) products are engineered to address many of these challenges. Their lightweight construction, corrosion resistance and slip-resistant surfaces make them an ideal choice for demanding industrial environments — helping to improve workplace safety while reducing maintenance and supporting long-term performance. 

But choosing the right type of FRP is just as important as choosing FRP itself.

Why Choosing the Right FRP Product Matters

Although they’re all manufactured from FRP, structural shapes, molded grating, pultruded grating and stair treads are engineered for different applications. Selecting the right product helps ensure you’re addressing your facility’s specific safety challenges while maximizing long-term value.

Rather than asking, “Which FRP product should I use?” start by asking:

• Will this component support structural loads?
• Is the area exposed to moisture, chemicals or corrosion?
• Are slips and falls a concern?
• Will the material need to span long distances or support heavy loads?
• Do I need standard components or a custom-fabricated solution?

Your answers will help determine which FRP solution best fits your application.

FRP Structural Shapes: Best for Load-Bearing Structural Applications

If your project requires framing or structural support, fiberglass structural shapes are typically the right place to start.

Designed for load-bearing applications, structural shapes provide reliable structural support in demanding industrial environments while resisting corrosion that can shorten the life of traditional materials like steel.

Structural shapes are commonly specified for applications such as:

• Equipment platforms
• Pipe racks
• Mezzanines
• Stair towers
• Crossovers
• Handrail systems
• Structural framing

Because FRP structural shapes are significantly lighter than steel, they’re often easier to transport, fabricate and install. Their reduced weight can also help minimize manual handling and lifting requirements during installation. They also resist corrosion in many chemical and moisture-rich environments, making them a dependable long-term solution for demanding industrial facilities.

Molded FRP Grating: Best for Walkways, Trench Covers and Drainage Areas

When the priority is creating a safer walking surface, molded FRP grating is often the preferred choice. Its one-piece construction delivers multidirectional strength while providing an aggressive slip-resistant surface that performs well in wet or corrosive environments.

Molded grating is commonly used for:

• Walkways
• Elevated platforms
• Trench covers
• Drainage areas
• Water and wastewater facilities
• Chemical processing plants
• Manufacturing environments

Unlike traditional metal grating, molded FRP won’t rust and continues providing dependable traction even when exposed to moisture, chemicals and harsh industrial conditions.

Pultruded FRP Grating: Best for Long Spans and Heavy Loads

Some applications require greater spanning capability or increased load capacity without sacrificing corrosion resistance. Pultruded FRP grating is specifically engineered for these situations. Manufactured using structural bearing bars, it delivers exceptional strength while remaining lightweight and resistant to corrosion.

Pultruded grating is often selected for:

• Long-span walkways
• Elevated access platforms
• Heavy-duty industrial applications
• Equipment access areas
• Projects requiring ADA-compliant options

When structural performance and worker safety are equally important, pultruded grating offers an ideal combination of strength, durability and slip resistance.

FRP Stair Treads: Best for Safe, Slip-Resistant Stair Access

Stairways often become one of the highest-risk areas within a facility, particularly where moisture, chemicals, oils or debris are present. FRP stair treads help improve footing with durable slip-resistant surfaces while resisting corrosion that can deteriorate traditional steel stair systems over time.

Fiberglass stair treads are frequently installed on:

• Industrial stair towers
• Equipment platforms
• Exterior stairs
• Manufacturing facilities
• Chemical processing plants
• Utility and infrastructure projects

For existing stairways, FRP tread covers can often be installed directly over steel or concrete steps, providing an economical way to improve traction and extend service life without replacing the entire staircase.

Custom Fabrication for Unique Applications

No two facilities are exactly alike. While standard FRP components meet the needs of many projects, others require custom fabrication to accommodate existing equipment, unique layouts or specialized applications.

OSCO Safety offers fabrication and assembly services to help simplify installation and reduce field labor. Using CNC fabrication technology, components are manufactured to tight tolerances for precise fit and easier assembly. Depending on project requirements, OSCO can also provide subassemblies — or fully assembled systems — ready for installation.

Whether you need a custom platform, staircase or structural assembly, fabrication support helps keep projects moving while minimizing installation time.

Common Questions When Selecting FRP Products

Every facility has unique requirements, but many customers come to OSCO with similar questions, including:

• What sizes and profiles are available?

• What are the current lead times?
• Which material is best for corrosive environments?
• What load capacities are available?
• Are accessories and hardware included?
• Can products be fabricated to fit our application?
• Do you offer complete structural systems?

Working with an experienced safety partner can help answer these questions early and ensure you’re selecting the right solution before installation begins.
