Steel Grates 18″ X 36″ X 1.5″

The Importance of Hot-Dip Galvanization During the Manufacturing Process

The exceptional longevity and performance of our 1.5″ steel trench grates are the direct result of a meticulous and crucial manufacturing step: hot-dip galvanization. This process is the gold standard for protecting steel from its most relentless enemy — corrosion. Once impeccably clean, the grate is completely immersed in a bath of molten zinc.

The molten zinc reacts with the iron in the steel to form a series of zinc-iron alloy layers. The layers are harder than the base steel itself, creating an incredibly tough and abrasion-resistant barrier. By the end of the hot-dip galvanization process, every part of the grate — every edge, corner, and crevice — is uniformly coated, offering complete and total protection that other metal coating methods, like electroplating or painting, simply cannot match.

The Benefits of 18″ x 36″ x 1.5″ Galvanized Steel Bar Grating

Choosing the right material and design for your trench covers is a decision that impacts safety, longevity, and long-term costs. For this reason, we’ve designed our 18″ x 36″ x 1.5″ galvanized steel grates to be a long-lasting and cost-effective solution.

Unmatched Strength

Carbon steel is renowned for its high tensile strength, and when fabricated into a bar grate, it creates a structure with an exceptional strength-to-weight ratio. The 1.5″ thickness (bar height) provides the necessary rigidity to support substantial loads without bending or breaking, ensuring a safe and reliable surface for years to come.

Low Maintenance

By creating a tough, bonded barrier against rust and corrosion, the hot-dip galvanization process dramatically extends the service life of the steel. Unlike painted grates that require frequent touch-ups and eventual replacement due to flaking and rust, our 18″ x 36″ x 1.5″ galvanized steel trench grates will endure for decades with virtually no maintenance required.

Cost-Effectiveness

While the initial investment for a high-quality galvanized grate may be higher than that of some other alternatives, its total cost is significantly lower. The extended lifespan and elimination of maintenance costs mean that, over the long term, our 18″ x 36″ x 1.5″ galvanized steel grates are the most economical choice in many applications.

The Many Uses of Heavy-Duty 18″ x 36″ x 1.5″ Galvanized Steel Grates

The specific dimensions and robust construction of our 18″ x 36″ x 1.5″ galvanized steel grates make them one of the most versatile grating products on the market. Their size is ideal for covering trench widths found in a multitude of settings, while the 1.5-inch thickness ensures they can handle significant load requirements, from pedestrian foot traffic to heavy-duty vehicular loads.

You may find these grates being used in the following applications:

• Industrial Facilities: Factories and processing plants require trench grates that can withstand heavy machinery, chemical spills, and water accumulation. The strength of our steel bar grating prevents damage from forklifts and other vehicles, while the galvanized coating provides essential protection against a wide range of corrosive substances.
• Commercial Parking Lots and Garages: Proper drainage in parking areas is essential to prevent water from pooling and to minimize the chances of damage to concrete and asphalt surfaces. Our 18″ x 36″ x 1.5″ galvanized steel grates are ideal for long trench drains in these areas.
• Municipal Infrastructure: Cities use these trench grates in medians and pedestrian walkways. Their durability makes them ideal for withstanding constant exposure to rain, debris, and vehicle weight.
• Sports Complexes and Stadiums: Outdoor stadiums and arenas depend on robust drainage to handle stormwater and large crowds. These trench grates are strong enough to support heavy foot traffic and equipment.
