UPVC Gutter Down Pipe system complies where applicable with the requirements of BS4576:1970 and it is suitable for internal and external installations. The complete range of pipes and fitting are available in 3 sizes; 110mm, 160mm and 200mm, and they are manufactured in white color only. The Gutter Down Pipe are produced in 2 different types of wall thickness and a table is compiled as below:

Domed roof outlet grating

Domed roof outlet grating is designed with a removable push fit high dome grating to prevent blockage and it is made with high quality UPVC material with ultra violet stabilizer. This grating is offered with all the inherent advantage of plastics, strength, lightness and resistance to impact and corrosion. The grating is strong enough to withstand normal foot traffic. It is suitable to install in the reinforcement concrete roof and scupper drain or metal gutter.

Balcony drainage outlet

Balcony drainage outlet is designed with a vertical inlet grating to prevent blockage and it comes with an internal build in funnel to prevent the rainwater to flush out from the upper floor. It is recommended to be used in the multi storey apartments and low cost flats which the rainwater Gutter Down Pipe are installed exposed and it is also suitable for corridor and car park areas. With this special design fitting, the Gutter Down Pipe can discharge water in a single pipe system and it is neat in appearance.

Access pipe

Access pipe is to provide a big twist lock access door for cleaning and maintenance. The diameter of the access door is designed the same size with the down pipe, so that is easily accessible to any part of the down pipe. It is recommended to install this fitting together with the down pipe before it is connected to the underground drainage pipe (just above the ground floor level).

Pipe sleeve

The pipe sleeve is designed with many external ribs to prevent water from leaking and seepage along the external smooth surface of the UPVC pipe when inserting it into the concrete floor slab. It is suitable to use for UPVC Gutter Down Pipe system and also for soil, waste and ventilation system. The complete sizes are ranging from 32mm to 200mm, they are made to comply with BS5255:BS4514 and BS4576.

91° bend with spigot end

Specially designed bend with one spigot end (male end) for horizontal Gutter Down Pipe to run very closed to the concrete floor slab (ceiling). It is just solvent welded directly into the pipe sleeve which casted into the slab. With this way of installation, it gives a higher head clearance and also neat in appearance.

Offset bend

Bend with one spigot end can directly welded through solvent cement into the socket of the other bend. It will minimize the distance of “W” to form a narrow offset.

Aluminum pipe fittings are widely used in plumbing activities in today’s construction projects. The light weight and corrosion resistance of aluminum has made the aluminum pipe fittings a good choice especially in the use with aluminum pipes. Pure aluminum also comes with a low tensile strength and is the most important factor in making a good choice when resistance to corrosion is important. However, the aluminum easily forms alloy with elements like zinc, copper, silicon, manganese, etc, and the alloy is widely used for making fittings of increased strength and hardness.

Application wise, aluminum pipe fittings are widely used and applied in various applications, household plumbing, railings, racking, store fixtures, lighting grids, safety barriers, guardrails, hand rails and so on.

Apart of the wide range of applications, aluminum pipe fittings are available in multiple sizes and shapes, multiple type of finishings, as well as it is highly adaptable to the environment where it can be used either indoor or outdoor.

Pipe or piping is a cross hollow cylinder, which is used as a structural component. Pipe can be used for internal and external. Usually internal pipe is installed in the bath room, toilet, kitchen, above ceiling and etc, while external pipe is mostly used in underground. These is tonnes of types of pipe in the market and piping construction, such as copper pipe, steel pipe, polyethylene pipe, unplasticised PVC (UPVC) pipe, ductile pipe, cast iron pipe, galvanized pipe, poly pipe, concrete pipe, aluminum pipe, stainless pipe, metal pipe and etc. All of them have different uses and features.

All the pipes have many different types of size, it’s generally specified by the internal diameter. The cost or rate for all the types of pipe and sizes of them are totally different, when the piping supplier quotes you a rate, the rate will be following by its’ material of pipe and its’ nominal diameter.

Other than the materials of pipe that have been listed above, pipe can also be made from concrete or ceramic. For pipe which is made from UPVC, is usually used inside the building for bath room, toilet and kitchen and etc, basically UPVC is light weight, chemical resistance, non-corrosive properties, and ease of making connections and normally used for drinking water contribution. While for concrete and ceramic pipe, are usually used for low pressure applications such as gravity flow or drainage. The types of pipe used are depending on location and purpose that the pipe to be installed.

Installation pipe has to be done by specialize piping contractors because it requires variety of specialized tools, techniques, parts, pipe joints, pipe fittings and etc. Normally the cost for pipe installation is higher than the price for piping materials. Usually pipes are joined by welding or by using pipe threads, so various pipe fittings are needed during the installation process.
