Pleasant Mount Welding, Inc.'s aluminum covers are an attractive and structurally sound alternative to traditional aluminum diamond plate cover systems. We offer two different aluminum flat panel cover systems, a Standard-Duty Interlocking Cover and a Heavy-Duty Plank Cover. Utilizing custom extrusions, we can create fixed and hinged cover panel configurations for a variety of uses including odor control, protection from contaminants, and preventing UV exposure. We create innovative aluminum covers that offer cost-effective, long term solutions for architectural, municipal, and industrial storage applications. Our flat panel covers are widely used in the water and wastewater industries due to their chemical resistance, minimal lifetime maintenance requirements, and low construction cost. Every PMWI aluminum cover is custom designed in accordance with specific project specifications and engineered to meet any snow, wind, and suspended load requirements. Pleasant Mount Welding, Inc.'s competitive advantage is our quality reputation, unmatched experience, and the fact that we provide the complete package - we design, engineer, detail, and fabricate all of our covers in-house.

Water & Wastewater Reservoir Covers

The public's growing concern for clean water is pushing governments to implement legislation regarding water quality and municipal practices for protecting our environment.  Storage facilities are being required to cover finished water reservoirs to help keep out contaminants. Our team of specialized engineers are experienced in creating custom solutions for covering clarifiers, reservoirs, sludge holding tanks, and many other storage facilities with our innovative aluminum covers. Our cover hinges allow for easy access to weirs, basins, blowers and any other equipment located below the covers. Our flat panel covers provide great odor control and a safe working environment for plant operators. PMWI aluminum covers require little to no lifetime maintenance - this results in lower plant preservation costs and frees up valuable plant resources. Our covers are very durable and strong enough to handle large loading requirements, allowing for safe navigation throughout the plant.
