ATT Manhole Cover without gas lifters - square shape and checker plate

The ATT Square Manhole Cover without Gas Lifters and Checker Plate is a reliable and robust access solution developed for architects, engineers, and construction professionals involved in the planning and execution of public, industrial, and urban infrastructure. This product is particularly suited to areas where lifting assistance is not required, and access is needed less frequently, such as in promenades, roadways, utility zones, water treatment facilities, or technical service areas.

Made from high-quality stainless steel—including AISI 304, AISI 316, and the corrosion-resistant AISI 316TI—this manhole cover ensures long-term durability, even in environments exposed to high humidity, chemicals, or mechanical wear. Its pressed design and solid checker plate surface offer increased resistance to slipping, making it suitable for both pedestrian and light vehicular traffic.

The simplicity of the cover’s construction, with minimal welded joints, supports hygienic conditions and enhances long-term structural integrity. Its compact form enables straightforward installation, while gas-tight and watertight sealing provides protection for underlying utilities against moisture ingress, contamination, and odor release.

The checker plate surface adds mechanical strength and slip resistance, which makes this product an effective and low-maintenance solution in both technical and aesthetic terms. It is a proven component in projects where function, safety, and discreet appearance are equally important.
