Metal / Steel Products for Wastewater Treatment
Bar Grating for Wastewater Treatment Facilities
Bar grating is a foundational product in wastewater treatment plants, where safety and long-term durability are essential. It is commonly used for walkways, overhead platforms, trench covers, stair treads, and crossover platforms throughout water treatment facilities.
Marco Specialty Steel supplies and fabricates welded and press-locked bar grating in carbon steel, stainless steel, aluminum, and specialty alloys like Monel, Inconel, and Hastelloy. Fabrication services include custom panel sizing, stair treads, nosing, banding, and cutouts.
Expanded Metal for Wastewater Treatment Facilities
Expanded metal provides strength, visibility, and airflow while reducing weight. In wastewater facilities, it is frequently used for catwalks, fencing, equipment enclosures, and guard panels. Marco Specialty Steel supplies standard, flattened, and grating-style expanded metal.
Perforated Metal for Wastewater Treatment Facilities
Perforated metal plays a critical role in wastewater treatment applications involving screening, filtration, ventilation, and equipment protection. It is commonly used in screens, intake protection, enclosures, and safety-related panels throughout treatment plants.
Hole size, pattern, and material selection are often dictated by flow rates, particle size, and corrosion exposure. Marco Specialty Steel custom punches perforated metal with round, square, slotted, or engineered hole patterns to meet functional requirements. Panels can be fabricated for direct installation into screening systems, equipment housings, or support frames.
Wire Cloth (Wire Mesh) for Wastewater Treatment Facilities
Wire cloth is widely used in wastewater treatment plants for screening, filtration, and equipment protection. It supports solids separation processes and helps protect mechanical systems while allowing controlled fluid flow.
Woven wire mesh is commonly specified for clarifiers, settling tanks, screening systems, and testing applications where precise openings and consistent performance are required. Wire mesh is also used as machine guards and protective barriers around equipment. Marco Specialty Steel supplies and fabricates wire cloth in a range of opening sizes, wire diameters, and alloys to support both process-driven and safety-related applications.
Safety Plank Grating for Wastewater Treatment Facilities
Wastewater treatment facilities rely on safety grating to provide enhanced slip resistance in environments where moisture, chemicals, and biological matter are present. Treatment facilities commonly use it for stair treads, ladder rungs, and crossover platforms.
Marco Specialty Steel supplies and fabricates planks, walkway channels, and stair treads to support safe pedestrian walkways while meeting load and dimensional requirements specific to wastewater infrastructure.
Fiberglass Grating (FRP) Products for Wastewater Treatment
FRP Grating and Structural Systems for Wastewater Treatment Facilities
Fiberglass grating (FRP) is widely used in wastewater treatment plants due to its corrosion resistance, and it will not rot or conduct electricity. This product is ideal for areas that stay wet. The wastewater treatment industry relies on fiberglass grating for its non-slip properties, helping ensure safe worker access to water towers, clarifier tanks, sedimentation basins, and digester tanks.
Marco Specialty Steel supplies and fabricates molded and pultruded FRP grating panels, stair treads, ladder systems, handrails, and structural shapes. These systems are commonly used around tanks, basins, and other continuously wet areas where steel corrosion is a concern.

Metal Materials for the Wastewater Treatment Industry
Marco Specialty Steel only sources high-quality material products:
- Stainless steel: This material has been used in the wastewater treatment industry for the last 50 years. Stainless steel offers high corrosion resistance, especially against corrosion due to microorganisms used in the treatment process. Stainless steel provides anti-corrosive properties, which minimize the degradation or loss of metal in walkways, structurals, stairs, and crossover platforms in wastewater treatment facilities, and is extremely durable during maximum flows of water. Stainless steel for wastewater applications is a good option.
- Galvanized steel: For environments that are near water, galvanized steel is an ideal material. For the best corrosion protection, we offer the A653 grade with a tensile strength of 58,000 to 79,800 psi.
- Carbon steel: Carbon steel is more prone to corrosion; therefore, stainless steel is used more in the wastewater industry.
- Aluminum: This corrosion-resistant material is commonly used for walkways, elevated platforms, and catwalks.
- Nickel alloys: Wastewater treatment plants use nickel alloys for high-pressure pipework, valves, and pumps

Frequently Asked Questions About The Wastewater Treatment Industry
Below are some of the most common questions we receive about our products and fabrication for the wastewater treatment industry.
Does Marco Specialty Steel supply products for wastewater treatment facilities along the Gulf Coast?
Yes. Marco Specialty Steel supplies grating, wire mesh, perforated metal, hex metal, expanded metal, and fiberglass grating for wastewater treatment facilities throughout the Gulf Coast region.
What products does Marco Specialty Steel supply for wastewater treatment plants?
Marco Specialty Steel supplies bar grating, fiberglass grating (FRP), safety grating, wire mesh, perforated metal, expanded metal, and hex metal for wastewater treatment facilities. These products are commonly used for walkways, platforms, screening equipment, filtration systems, and structural components throughout treatment plants.
What materials work best for wastewater treatment plants in coastal or Gulf Coast environments?
Wastewater treatment plants located along the Gulf Coast must consider high humidity, salt air, and highly corrosive conditions. Materials such as stainless steel, galvanized steel, aluminum, and fiberglass grating (FRP) are commonly used because they provide strong corrosion resistance and long service life. In more demanding environments, specialty alloys such as Monel, Inconel, and other nickel-based alloys may also be used for components that require exceptional resistance to corrosion and chemical exposure.
What types of grating are used in wastewater treatment plants?
Wastewater treatment facilities commonly use bar grating, fiberglass grating (FRP), and safety grating for walkways, platforms, trench covers, and equipment access areas. These grating products provide strength, drainage, and slip resistance in wet environments.
Where is bar grating typically used in wastewater treatment plants?
Bar grating is commonly used for walkways, catwalks, platforms, trench covers, and stair treads throughout wastewater facilities. Its open design allows water and debris to drain while maintaining strong load-bearing support.
How is wire mesh used in wastewater treatment systems?
Wire mesh is frequently used in filtration systems, screening equipment, debris separation, and protective guards. Woven wire mesh can help remove solids and contaminants during the treatment process.
What role does perforated metal play in wastewater treatment applications?
Perforated metal is used for screening, filtration components, drainage panels, equipment guards, and ventilation panels. The precise hole patterns allow controlled flow of liquids or air while retaining solids.
What are the advantages of fiberglass grating in wastewater environments?
Fiberglass grating (FRP) is commonly used in wastewater facilities because it resists corrosion from chemicals and moisture. It is lightweight, durable, and often used for walkways and platforms in highly corrosive areas.
What safety features are important for wastewater treatment walkways?
Walkways and platforms in wastewater plants must provide slip resistance, drainage, and strong structural support. Products such as bar grating, safety grating, and grating stair treads help improve worker safety in wet environments.
Can Marco Specialty Steel fabricate custom components for wastewater treatment facilities?
Yes. Marco Specialty Steel can fabricate custom components from grating, perforated metal, expanded metal, and wire mesh to meet project specifications. Our Houston facility provides cutting, forming, welding, and finishing services to support new construction, plant upgrades, and maintenance projects.
Why are open-grid grating products used in wastewater facilities?
Open-grid grating allows water, sludge, and debris to pass through the surface instead of accumulating. This helps reduce slipping hazards while keeping walkways and work platforms cleaner.
