600×600 mm SMC Manhole Chamber with B125, C250 & D400 cover rating for secure and modular underground access.
The FAB-MH600-B125C250D400 is a high-capacity manhole chamber engineered to support rigorous urban and industrial environments. With a 600×600 mm clear opening and external dimensions of 760×760×900 mm, this unit is built entirely from SMC (Sheet Molding Compound), delivering excellent mechanical resistance, corrosion protection, and weight savings over traditional cast iron alternatives.
Certified for Class B125, C250, and D400 loading under BS EN124 standards, this chamber is suitable for use in heavy-duty vehicular traffic areas such as city streets, sidewalks, utility corridors, and telecom distribution zones. Its composite construction resists rust, UV degradation, and fuel or chemical exposure—while the anti-slip surface and locking system provide secure and safe access.
Modular and stackable by design, the FAB-MH600-B125C250D400 simplifies shipping and installation logistics. It is fully manually deployable, reducing total project cost and enabling use in locations where machinery access is limited.
This manhole chamber is an ideal choice for municipalities, utility companies, and telecom operators seeking long-term reliability in their underground infrastructure—engineered by Fibramérica for high-performance networks.
