Our services


Due to high volume of theft and recycling of the material such as cast iron and metal products. SMC Composite material will eliminate this theft and therefore has no second use value on the product. Sheet Molding Compound material is non-metallic, non-sparking. It will never rust for its good wear and corrosion resistance. it is also light which makes it more convenient to transport, install and repair.

2.0 Lockable SMC Composite Manhole Cover and Frame

Lockable SMC Composite Manhole Cover is made from sheet molding compound and design solely to improve workability and adapt to circumstances with theft and vandalism behavior.


  • SMC stands for Sheet Molding Compound.
  • It is composed of resin, fiberglass and other chemical polymer.
  • This is a raw material for mold pressing.


  • Flame Resistant – passed the control product safety standards such as UL94 flame rating.
  • Corrosion resistant – has undergone the same strict performance requirements of pumps among other underground appliances that are in contact with corrosive environments.
  • Electrical Insulators – has a dielectric attributes of supporting electrostatic fields.
  • Zero scrap value – burglar proof with next to nothing resale value; industry scrap metal reduced.
  • High strength to weight ratio compared to or with the heavy concrete manhole. Composite chambaer is quite lightweight and no need for extra large machinery assistance. One is enough to lift the chamber section.
  • The weight of composite lockable cover especially SMC lockable cover is lighter, so it is more convenient to transport, install and repair.
  • The minimum lifespan is 30 years free of maintainance


  • Color, logo, panel, loading and dimensions can be designed according to the requirements of customer.

  • Sheet Molding Compound made up of composite materials that have long life span – need little or no maintenance.

Optic Fibre Cable

We will provide sample for your inspection and validation. If you are happy with the sample, we will move ahead and produce the products according to your requirement. If you are not happy with the sample, we will work on product manufacturing techniques and remake the sample for you and make sure you get the product of your expectation in short period. However, we do not have any experience where our customers do not satisfy our samples.

FRP Poles

Creative outlines for decorative FRP poles make us unique and the best lighting lamps and poles suppliers in the industry. All our poles carve out the precision architectural taste of the clients. These are anti rust, anti chemicals, easy to install and cost effective range of FRP lighting poles.


  • Fiberglass Reinforced Plastics
  • A composite is the combination of a reinforcement material in a matrix.
  • Fiber reinforced plastics (FRP)  are a subdivision of the composites field in which the matrix is a polymer and the reinforcement is fiber.
  • In this particular case, the reinforcement is fiberglass.

Advantages of FRP Lighting Pole

  • Non-conductive and Anti-static -   FRP is non-conductive ideally suited for electrically hazardous locations.  FRP is an excellent electrical inhibitor which is particularly important in  underground and offshore applications.
  • Corrosion Resistance –  Unlike carbon steel, concrete, wood and other conventional materials,  FRP will not corrode and can be exposed to continuous submersion,  splash, spills, fumes or gases, and still maintain its integrity.
  • Light weight and low installation cost -   FRP pole is significantly light weight comparing to steel pole to reduce fabrication, transportation and installation costs. Installation can often be done by simple hand tools, reducing the need for costly equipment and labor costs associated with heavy lifting, cutting and welding.
  • Maintenance free -  FRP will not rust, corrode or fade and therefore do not require maintenance. Special UV inhibitor are integral to the products for withstanding the harsh sun exposure.
  • Aesthetics, smooth surface with good finishing. Also can be color matched to suit any environment
  • Non-sparking and Fire resistance –  While other materials may cause a fire or an explosion from sparks produced from accidental dropping of tools onto the metal surface, FRP is ideally suited for those installations where hydrogen or other combustible gases may be found as it does not produce sparks. Shanghai Tung Hsing FRP pole can achieve self-extinguish property by adding fire retardant agent.
  • Superior Strength -  The high glass-to-resin ratio of FRP creates materials which are incredibly strong, with excellent load bearing capabilities. Combined with other properties, FRP will far outlast traditional materials.

FRP ADSS Pole Spec Sheet

  • To withstand wind speed of 40m/sec & 60m/sec equivalent to Beaufort Scale Force 12 & 17
  • Design verification using “Finite Element Analysis”
  • Based on 60m/sec wind speed, the pole top deflection induced by the wind acting on the pole shall not exceed 10% of the pole length

Below table shows applied loading is calculated based on wind speed of 60m/sec according to ANSI.
