FCST-TH-SMC15
The FCST-TH-SMC15 is a modular composite telecom manhole chamber designed for underground cable and duct access applications.
Made from SMC/BMC composite materials, the chamber provides a lightweight alternative to traditional brick-built chambers. Its modular sectional design allows contractors to adjust the chamber depth on site by stacking sections according to the required burial depth.
The chamber is designed for EN124 D400 load applications and can be used in underground telecom, municipal, power, road, water, and drainage infrastructure.
With lightweight components, pre-formed duct entry points, and a modular construction method, the FCST-TH-SMC15 helps simplify installation and reduce on-site labor requirements.
The FCST-TH-SMC15 is designed with an EN124 D400 manhole cover load grade, making it suitable for heavy-duty underground infrastructure applications.
The chamber sections can be stacked to achieve the required installation depth. This allows contractors to adapt the chamber configuration to different burial depths without modifying the main chamber structure.
The chamber uses SMC/BMC composite materials. Individual components are lightweight enough to be manually handled and assembled on site, helping reduce the need for heavy lifting equipment.
All four sides are provided with reserved openings of up to 110 mm. The openings can be adjusted during installation according to the actual size of HDPE pipes, silicon pipes, or microducts.
The prefabricated modular structure avoids the need for traditional brick construction and on-site concrete work. According to FCST installation information, the complete chamber can be installed from excavation to reinstatement in less than one hour, depending on site conditions.
Transverse and vertical stiffeners are arranged around the outside of the chamber. When combined with properly compacted surrounding soil, the external structure helps keep the chamber stable during installation and after backfilling.
The FCST-TH-SMC15 has a designed service life of up to 30 years for underground infrastructure applications.

Compared with traditional brick-built chamber construction, the FCST-TH-SMC15 uses a prefabricated modular structure.
This means contractors can:
Handle → Stack → Connect → Backfill → Reinstate
without building the chamber section by section with traditional masonry methods.
The lightweight components also make manual handling and on-site assembly easier.
Prefabricated construction can reduce on-site installation costs by up to 80%, while the complete chamber installation can be completed in less than one hour under suitable site conditions.
The FCST-TH-SMC15 is a modular composite telecom manhole chamber for underground cable and duct access. It can be used for fiber optic networks, microduct systems, municipal infrastructure, power utilities, road infrastructure, water, and drainage applications.
The chamber is designed with an EN124 D400 cover load grade. The appropriate installation method and surrounding civil structure should be determined according to the project design and site conditions.
Yes. The modular sections can be stacked according to the required burial depth, allowing contractors to adjust the chamber configuration during installation.
The chamber has reserved openings on all four sides, with openings available up to 110 mm. The openings can be adjusted on site according to the actual size of HDPE pipes, silicon pipes, or microducts.
The chamber panels are available in SMC or BMC configurations. The cover is available in SMC or ductile iron, depending on the selected configuration.
Yes. Optional FOSC mounting frames are available for securing fiber optic splice closures inside the chamber.
Yes. The optional FCST Cross Cable Rack can be installed inside the chamber for fiber cable slack management.
The specified working temperature range is -40°C to +65°C, with a storage temperature range of -40°C to +70°C.
The FCST-TH-SMC15 has a designed service life of up to 30 years.
The FCST-TH-SMC15 modular composite telecom manhole chamber combines a lightweight SMC/BMC construction with a stackable design for flexible underground installation.
With EN124 D400 load grade, up to 110 mm duct entry openings, manual handling capability, optional fiber management accessories, and a 30-year designed service life, it provides a practical solution for underground telecom and utility infrastructure.
