en124 c250 manhole cover
About
us:
We supply all size all dimension FRP composite manhole cover, which
can be designed according to user's demands.
Compared with other composite materials manhole covers,
Burglarproof manhole cover has the following specialties:
Â
Manhole Cover
Structure:
Using the structure of pot bottom style (loading equally),other
than the one of ribbing style (loading centrally),the strength
supporting area will extend by more than ten or dozens of times.
Therefore, the ability of strength sustaining will be more
excellent.
Â
Manhole Cover
Materials:
Our Burglarproof Artistic manhole covers (shorted for FRP manhole
cover) are made from composite materials such as glass fiber,
resin, quartz, corundum etc..
Applying wear-resistant and climate-resistant materials on the
relief sculpture layer so that the products can be long-term used
under different environment.
Applying continuous reinforced fiber on the structure layer to
ensure the products having sufficient sustaining ability. While
some of other composite material manhole covers (for examples, BMC
manhole cover) do not contain reinforced fiber, or just contain
short fiber (the intensity of short fiber is 20-30% of continuous
fiber);
Â
Manhole
Cover Design:
Infusing the manhole covers with the art of relief sculpture,
designing individually to meet clients demands with artistic
effect, promoting the culture feeling of our composite material
manhole cover, the material is FRP, shorted for Fiber Reinforced
Plastic;
Â
FRP manhole cover material quality
Our FRP
products are made of:
-Unsaturated polyester resin (UP) (Iso type resin, vinyl ester
resin)
-Glass fiber (E-glass 2400 Tex)
-Quartz
-Corundum
-Antioxidant
-Firming agent
-Promoter
-UV additive
-Ethylene-propylene-diene-monomer
-Cr13
-Other auxiliary materials
Â
Application Temperature
Scope:
The materials used to manufacture the manhole covers are important,
that is why we only use quality materials. The main material that
contribute to the product application temperature is the non
saturated polyester resin. It belongs to the thermosetting resin,
the performance after its solidification is as follows:
Longitudinal strength:250-600Mpa;
Compressive strength:300-600Mpa;
Stretch modulus:25-35Gpa;
Break elongation ratio:1.3-10.0%;
Bending strength:700-1400Mpa;
Curving module:25-35Gpa;
Poisson-ratio:0.35;
Relative density:1.11-1.15;
Water-absorptivity(24h):10-30mg;
Volume resistivity.1*(1012-1014)cm
Unsaturated polyester resin for the reinforced plastics uses the
most universal resin, general application temperature in -40~80. If
there is any special request, we may introduce a special function
structure to cause its temperature to be lower or higher. When the
temperature approaches-40, resin brittleness will occur. When
temperature surpasses 80 for a long period of time(special heat
resistant resin to be an exception) has the possibility to become
soft or degrades. Therefore, our products application temperature
is in the principle scope of -40~80.

Â
The Service
Life
From the resin heat resistance view, our products under the normal
temperature uses, its service life amount to above for 50
years.
The GRP manhole cover uses lamination compound craft on the surface
layer between 5-8mm, where it joins the antioxidant to bear the
marquis resin and it is filled by the aggregate of quartz, corundum
and anti-friction materials (this kind of material is uses for the
make grinding wheel). The surface of the manhole cover will not
have any attrition because the designed 5-8mm provide wear
resisting level extrapolation, it is possible to use above for 30
years.
The compound material of the manhole covers make sure that it could
withstand more than 2 million fatigue shocks. Official tests and
experiments have shown any problem on the heat resistance after
more than 3 years of exposure.
To increase the intensity of the products, solidification craft
processing is used after normal solidification process is done.
Although the resin has joined with antioxidant which will delay the
product from yellow stain, after a long period of time some yellow
stain will still appear. It is a normal condition and does not
affect the product. Our suggestion is to use color of natural stone
material where only minor color change will occur.
Our
company:
We are one of the leading manufacturers of manhole covers,
fasteners, pumps, motor shells and other castings and forgings. Our
products are made according to different standards, such as
ISO2531, EN545, EN14525, ISO4422, ISO7005, DIN3352, BS5163,
