Description

The 300 SQ Heavy Duty Cover and Frame is a high quality polymer concrete access cover manufactured to SABS specifications for municipal, utility, telecommunications, industrial, and civil engineering applications. With a tested 135kN load rating, it provides secure and reliable access to underground infrastructure while delivering long-term performance in demanding service environments.

Its advanced polymer concrete construction offers exceptional resistance to corrosion, chemicals, moisture, UV exposure, and harsh weather conditions. Unlike traditional cast iron covers, it will not rust, crack, or deteriorate over time, helping to reduce maintenance requirements and lower lifecycle costs.

The precision-engineered cover and frame provide a secure fit, reliable load distribution, and dependable structural performance. Ideal for utility networks, telecommunications chambers, drainage systems, service access points, and industrial developments, it helps protect critical underground infrastructure while allowing safe and efficient access for inspections and maintenance.

The non-metallic design offers an additional advantage with zero scrap value, helping to reduce theft, vandalism, replacement costs, and service interruptions. Trusted by municipalities, contractors, engineers, and developers throughout South Africa, the 300 SQ Heavy Duty Cover and Frame delivers a durable, low-maintenance, and cost-effective solution for modern infrastructure projects.
