Rolling Shutter - Project, Technology , Patents, Market, Companies
- Milled Steel rolling shutters are fabricated from high-quality steel rods to operate on the same principles of rolling shutter. This shutter can be integrated with grills or perforated panels to achieve ventilation or see-through vision. It is easy to install. It is weather resistant. This roller shutter is the cost effective solution for any kind of application & prevent the shutter from rusting and helps to provide them with a long life.
- Aluminium Rolling Shutter is designed with extruded aluminium section & fabricated using superior grade aluminium. Aluminium shutters are available as both single wall and double wall with insulation. These roller shutters are light in weight, corrosion free and give the good aesthetic appearance.
- Polycarbonate or Transparent Rolling Shutter creates an aesthetic transparency throughout the area whereby visibility can be achieved from either side of the premise when the shutters are lowered. It is transparent, lightweight, and secured. Mostly they are made from polycarbonate but are very costly.
- The automatic rolling shutter is generally power drives. It is fitted with electric motor and gear box
- When the area of the opening is less than 10m2, the shutters are operated by applying manual pull or push. These types of the rolling shutter are known as push-pull type rolling shutters
- When the area of the opening is greater than 10m2 then the shutters are operated by reduction gear, connecting rod and winding handle or chain of pulley blocks. This type of roller shutter is known as mechanical gear rolling shutter.
- Grill rolling shutter is built of aluminium alloy or steel links of 0.9mm thickness assembled on rods. The grill can be made out of 8mm diameter mild steel or aluminium alloy round bars. These types of the rolling shutter are used where protection and safety, visibility and ventilation is also desired.
- The industrial rolling shutter is most commonly used where the environment is harsh with usage and has very large sizes. It is made from metal, aluminium and steel
- Window roller shutters Window rolling shutters are another popular variety of security shutters that come in a range of different styles and designs, and each has its own benefits.
- M.S. Strips of desired width are taken in coil form and fed to roller type sheet forming machine in which the rolling shutter profiles are formed. The spring steel wires are formed into springs shape in the spring coiling machine. The hand shearing machine and the press brake are used to frame fabrication. All the components are assembled and painted with red oxide primer.
- The product is to be fabricated and inspected as per ISI specifications i.e. IS : 6248. Beside, IS specification; there are customer’s specifications, which may be strictly followed too.
- Roller shutters have many applications, including doors for vans, garages, kitchens, schools, prisons and warehouses
- In areas that are frequently exposed to inclement weather, roller shutters are used as a method of insulation and can protect windows against hail damage.
- There is good demand for rolling shutters, as an item of common use in construction of shops, godowns, workshop sheds etc. They are sold directly to the users.
- Rolling shutters are requires for every new shop / enterprise coming in any area. On an average in every city around 400-500 new shops grow every year. If we club the demand of rural area, it would be around 2000 numbers every year. In addition to rolling shutters, concern would utilize its fabrication facility in fabrication of other products as per market demand on job to bob basis.
Concrete Coatings
- Modern concrete is a mixture of Portland cement, water, fine and coarse aggregate, and, in some cases, various admixtures. When properly formulated and mixed, the cement cures and hardens to a dense solid in the chemical process of cement hydration.
- But the matrix of cement and aggregate can deteriorate or otherwise sustain
damage. Concrete can be highly porous, allowing water to penetrate; if freezing occurs, the resulting expansion can weaken the concrete from within. Moisture can carry salts into the concrete, causing damage or attacking the steel reinforcing rods embedded in the concrete. - Concrete has low tensile strength and ductility and adding reinforcement is necessary to resist stresses and strains in structural members. Steel fiber reinforcement provides superior resistance to cracking and crack propagation under any type of load by
compensating these shortcomings. - The chief function of a protective coating is to prevent moisture and oxygen from reaching the substrate.
- The chief function of a protective coating is to prevent moisture and oxygen from reaching the substrate.
- Coatings provide protection by forming a film that prevents damaging substances from working into the pores and capillaries of the concrete.
- Moisture content and movement loom large in success or failure of concrete coating and flooring application
- Polymer coating materials for concrete slabs may include various deck paints, epoxies, urethanes, acrylics, and other surface-applied liquid films.It is possible to increase the life of concrete floors by application of certain materials known as 'hardeners'
- Floor-hardeners are a mixture of cement, aggregates (quartz, carborundum or iron particles) and other additives. They consume the rising water from the green concrete, hydrates and gives a hard-wearing and dense surface. The floors, thus cast have becomes an extremely durable, abrasion-resistant surface over a period of time and provides a fairly tough and wear-resistant surface.
