But today let us talked about the SMC/BMC manhole cover of FRP/GRP:
SMC manhole cover:
SMC is the abbreviation of sheet molding compound. SMC has excellent electrical properties, corrosion resistance, light weight, and engineering design easy, flexible, etc. Its mechanical properties can be comparable with some metallic materials, which are widely used transport vehicles, construction, electronics/ electrical and other industries.
Without steel bar to enhance the load force:
BMC manhole cover
BMC are the abbreviation of sheet molding compound, short fiber. This raw material need to add steel bar to improve its load capacity. The toughness is not as good as the SMC material.
Composite materials have become an indispensable part of the current stage, especially in the hardware industry, including good covers, trench cover, power cover, tree protection, and other products that are inseparable from composite materials.
Its unique feature is that the material itself has no secondary use-value, which can greatly reduce the harm caused by theft of the product.
Excellent performance: Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
