The environment matters when choosing material.

Water and wastewater facilities can expose materials to moisture, chemicals, and other corrosive conditions. Depending on the application, FRP, stainless steel, galvanized steel, and carbon steel can each offer different advantages.

Marco Specialty Steel supplies a wide range of specialty metal and FRP products, with in-house fabrication for project-specific requirements.

Metal Products for Architectural & Public-Space Projects

Wire cloth, perforated metal, expanded metal, and bar grating can all play a role in schools, stadiums, commercial buildings, and public spaces.

Depending on the product, they can provide screening, ventilation, visibility, separation, architectural detail, or durable access surfaces.

Marco Specialty Steel supplies the material and provides in-house fabrication for project-specific requirements.

Where FRP Grating Wins Over Steel

In wet, corrosive, or electrically sensitive environments, fiberglass grating can be a better fit than steel.

FRP is commonly used in chemical plants, wastewater facilities, marine applications, cooling towers, and other areas where corrosion resistance and non-conductive properties matter.

Marco Specialty Steel stocks fiberglass grating and provides in-house cutting and fabrication for custom project requirements.

Expanded metal grating is built for walking surfaces.

Unlike standard expanded metal, catwalk grating uses heavier construction and a raised, oriented mesh pattern that provides additional traction.

Its one-piece construction also means there are no welded intersections, while the open design allows water, dirt, and debris to pass through.

It’s a strong option for catwalks, platforms, stairs, and industrial access areas.

Standard, flattened, or expanded metal grating?

Each type of expanded metal serves a different purpose.

Standard expanded metal has a raised, rigid surface for guards, screens, partitions, and other industrial uses. Flattened expanded metal is rolled smooth for a flatter profile, while expanded metal grating is built heavier for catwalks, platforms, stairs, and walking surfaces.

Marco Specialty Steel stocks expanded metal and provides in-house cutting and fabrication for custom requirements.
