KNEST MANUFACTURERS LLP PUNE, MAHARASHTRA - 411018
ALUMINIUM FORMWORK • This system is a set of formwork panel’s precisely manufactured from aluminium alloy and connected together to form a mold into which concrete is poured. • Panels are light weight avg 25kgs/sqm but very strong to withstand pressure up to 80 kN/m2.
When it is Suitable ..? • Mass Housing • No. of Repetitions Are More • Typical Floors • Fast Construction Required • High Quality • Column Less Structure • Highly Suitable To Load Bearing Structure (Shear wall)
Formwork assembly On leaving the factory all panels are clearly labeled to ensure that they are easily identifiable on site and can be smoothly fitted together using the formwork modulation drawings. All formwork begins at a corner and proceeds as per following sequence – 1. Wall panel erection 2. Wall top/beam panel erection 3. Soffit length panels 4. Deck panels 5. Kicker panels
Formwork assembly • SIMPLICITY – PIN AND WEDGE SYSTEM The panels are held in position by a simple pin and wedge system that passes through holes in the outside rib of each panel. The panels fit precisely, simply and securely and require no bracing. • Pin • Stub

Comparison between aluminum formwork & Conventional formwork system
Sr No Characteristic Aluminium formwork Conventional Formwork system system 1 Speed of construction 6 days cycle per floor 10-15 days cycle per floor 2 Quality of surface finish Excellent - plastering Bad is not required 3 Pre-planning of form work system Required Not Required 4 Type of construction Cast in situ cellular Simple RCC framed construction construction 5 Wastage of form work material Very less In great amount 6 Accuracy in construction Accurate construction Less than Aluform 7 Coordination between different Essential Not necessrily required agencies 8 Resistance to earthquake Good resistance Less than Aluform 9 Reusage value 250-300 15-20
Advantages of Aluminium Formwork Aluminium formwork is specifically designed to allow rapid construction of all types of architectural layouts. 1) Total system forms the complete concrete structure. 2) Custom designed to suit project requirements. 3) Unsurpassed construction speed. 4) High quality finish. 5) Cost effective. 6) Panels can be reused up to 250 times. 7) Erected using unskilled labor.
Advantages of Aluminium Formwork ▪ Easy to handle. ▪ Aluminum does not rust like steel; therefore, the Aluminium formwork can be reused hundreds of times. ▪ Formwork is made with an aluminium alloy, which has high tensile strength and is also very hard. ▪ Saving on overhead expenses due to speedy construction. ▪ Doesn’t require timber or plywood for construction activities so, it saves the environment. ▪ Casting of walls and slabs possible simultaneously. ▪ Doesn’t require skilled labour. ▪ Less debris generation. ▪ Higher scrap value. ▪ Carpet area will increase. ▪ Collect the best premium from the customer, because of 100% RCC buildings.
Why Knest Aluform?
Knest Advantage • At KnestAluminium Formwork we use state of the art modern design & manufacturing technology. • Our panels are designed to bear up to 80kN/m2 load which is highest amongst industry. • We use state of the art automated robotic welding – so our panels can last for very long time achieving very high repetitions. • W e use state of art plasma cutting technology allowing us to maintain very tight tolerances resulting in exact dimensions of concrete structures. • We use special imported tooling for punching holes in panels – resulting in absolutely no gap in our formwork panels – giving superior finish. • Our specialized 3D design software allows us to guide you from the very beginning and help in better formwork planning to save costs. • Our 3D execution drawings are very easy to understand for unskilled labors – resulting in faster cycle times. • We use state of the art tracking system to track every single part and child part in our factory resulting in faster production time and very high quality control. • Our manufacturing facility is amongst the largest in country, spread on 3 acres in industrially developed city of Pune.
