Una alternativa fuerte, no conductiva y ligera a las cubiertas de acceso de metal
La información se presenta en Inglés. Una vez traducida, está se actualizará. We're determined to keep safety our top priority. That's why we design our composite manhole frames and covers to deliver superior performance and safety for your unique infrastructure needs. Our heavy duty composite manhole covers are engineered to withstand roadway traffic, 50,000 lb proof load testing, and above industry standard fatigue testing to 2 million cycles at 16,000 lb.
We have built up over 25 years of tradecraft and know-how when it comes to producing our full line of composite products that are constructed of advanced fiberglass reinforced plastic materials.
Why Choose Composite Access Solutions by EJ
NON-CORROSIVE
 Sewer, storm, and wastewater environments can be highly corrosive. By its inherent nature, composite products will remain unchanged even in the most aggressive environments. This can apply to areas with exposure to sewer, petrochemical, gasoline, diesel, de-icing solutions, and salt water. |
DURABILITY AND STRENGTH
 Our premium composite products incorporate engineered fabric with glass fiber reinforcement that spans the entire width of the cover. This provides superior strength and product durability over other traditional methods that use short fibers. Heavy duty covers are tested to AASHTO M 306 heavy duty (H25) loading requirements for cast iron and withstand 2 million fatigue testing cycles. |
ERGONOMICS For areas that are frequently accessed, the reduced weight of composite covers improves the ease of access and increases overall worker safety. Heavy duty composite covers weigh between 30 lb (22" clear opening) and 82 lb (36" clear opening). We also offer lighter weight versions for off-street medium duty applications. |
NO SIGNAL INTERFERENCE
 Composite covers are constructed of advanced fiberglass reinforced plastic materials that won't interfere with the wireless communication signals. This is typically used in applications associated with water metering automation or electrical switching for smart grid technology. J-hooks can be installed to hang antennas from. |
NON-CONDUCTIVE
 Composite products do not conduct electricity, which makes them a safe choice for electrical utilities and municipalities that may have stray voltage concerns. Furthermore, when the product is placed over steam manholes, heat transfer is reduced. This provides additional insulating protection to pedestrians and utility workers. |
THEFT DETERRENT The scrap value of traditional manhole covers make them an easy target for theft. Missing manhole covers cause a real hazard for vehicular and pedestrian traffic. Since composite covers have no scrap value, they are less likely to be stolen. Additional locking options are available for added security purposes.. |
