DMC materials were first used in the former West Germany and Britain in the 1960s, and then developed greatly in the United States and Japan in the 1970s and 1980s respectively. BMC moulding plastics have excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and can meet the performance requirements of various products. BMC moulding plastics are widely used in automobile manufacturing, railway transportation, building accessories, mechanical and electrical products and other fields.
We know that BMC manhole cover material is short fiber which need to add deformed steel bar to improve load bearing capacity.
Deformed steel bar is important.
This picture we can see it clearly, no circle rings.
Follow picture is our factory produced:
For BMC manhole cover, the circle rings is good for its load bearing capacity. Quality of manhole cover is better than without deformed circle rings. When we purchasing manhole cover we need to know factory's steel bar and raw material is it good or bad.
