Advantages of our products:
1. No recovery value- It can solve the manhole cover stolen problem thoroughly.
2. Quality assurance- accepted insurance by the Pacific Insurance Company and ISO9001:2008 & SGS approved.
3. High load capacity according to BS EN124 Standard- Its high load capacity exceeds the ductile iron.
4. Free design with characteristic logo & various colors - It can be designed according to users' demands.
5. Long service life- It can be used more than 30 years and there is no any crack in the experiment of 2,000,000 fatigue shocks.
6. Well sealed- It can be used hermetically, and effectively prevent those poisonous gases leaking out from cesspool.
7. No jangle- There is neither jangle nor rebound when cars pass through.
8. Good wear and corrosion resistance-It will never rust and can resist weak acid, alkali, salt and seawater..
9. Temperature resistant- It can stand temperature ranging from -40 to 80 degree
Compared with other composite materials manhole covers, burglarproof manhole covers have the following specialties:
1. 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.
2. European Standard En124 Fiberglass Sewer and Drain Grates Material:
1) Our Burglarproof Artistic manhole covers (shorted for GRP manhole cover) are made from composite materials such as glass fiber, resin, quartz, corundum etc.
2) Applying wear-resistant and climate-resistant materials on the relief sculpture layer so that the products can be long-term used under different environment.
3) Applying continuous reinforced fiber on the structure layer to ensure the products sufficient load ability. While other composite material manhole covers (for example, BMC manhole cover) do not contain reinforced fiber, or just contain short fiber (the intensity of short fiber is 20-30% of continuous fiber);
3.European Standard En124 Fiberglass Sewer and Drain Grates Design:
Infusing the art of relief sculpture, image and color into the surface of manhole covers according to clients' demands for artistic effect, which promotes the culture taste of our products. 
4. GRP manhole cover material quality
Our GRP products are made of:
-Unsaturated polyester resin (UP) (ISO type resin, vinyl ester resin)
-Glass fiber (E-glass 2400 Tex)
-Firming agent
-UV additive
-Other auxiliary materials
5. European Standard En124 Fiberglass Sewer and Drain Grates Application Temperature Scope
1) 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:
2) Longitudinal strength: 250-600Mpa;
3) Compressive strength: 300-600Mpa;
4) Stretch modulus: 25-35Gpa;
5) Break elongation ratio: 1.3-10.0%;
6) Bending strength: 700-1400Mpa;
7) Curving module: 25-35Gpa;
8) Poisson-ratio: 0.35;
9) Relative density: 1.11-1.15;
10)Water-absorptivity (24h): 10-30mg;
11) Volume resistivity. 1*(1012-1014) cm
12) 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 to -40°C, 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.
13) C250 (can load 25tons) D400 (can load 40tons)
