Comparison of Boundary Wall / Compound Wall

Comparison & Advantages of Boundary wall with Concrete Extrusion Process V/S Conventional casting in mould Process.

Boundary Wall Panels & Columns are Manufactured By world’s Latest Concrete Extrusion Technology duly reinforced with Carbon steel wires

Sr. No.	Boundary Wall manufacturing by World’s Latest technology of Concrete Extrusion Process.	Boundary Wall manufacturing by Conventional casting in mould Process.
1	Investment: - Boundary wall Panel Extrusion M/c Size 50 x 300mm x 2 - 1 set & Supporting 'H' Column M/c size 150 x 150mm x 2 – 1 set, other Supporting machinery: - Concrete Mixer 17.5 CBM on stand with platform (with single horizontal shaft mixer having discharging gate installed Bottom of mixer, so that concrete falls directly into tray of manual cart) + Stressing m/c - 1 set + Manual Feeding Cart for concrete mix delivery – 2 Nos. + Slab Cutting m/c (for Panels & Column) – 1 Nos. + Wire Coil Dispensing stand - 3 set + Lifting & Shifting Trolley for shifting Extrusion M/c - 1 Nos. (Landed price Mumbai with Import duty only if complete set is purchased) Total Investment Rs. 21 lakhs. + Consultancy & Cost of land Development for setting plant.	Investment in steel Moulds used for Casting Process @ Rs. 65/kg for Panel mould = 255 Nos. of 7 ft. & Column mould 42 Nos. of 8 ft. Total Investment in Moulds + Drum mixture + Stressing m/c + feeding Bucket+ Grinder for Cutting wires + Trolley + Land development is Rs. 20 lacs. Total Investment Rs. 20 Lakhs.
2	Profit Margin - minimum 40% compared to moulded process	Profit Margin is less compared to extrusion process
3	Technology - Latest & Fastest.	Technology - Very Old & Absolute.
4	Return on Investment - within 4 months.	Return on Investment - Minimum 12 months.
5	5 times faster being Machine Production, Very easy & simple to manufacture.	Slow & Tedious being manual production.
6	Panel Weight of 7 feet is just 66.5 ggs being Hollow with same strength.	Panel Weight of 7 feet is just 73.5 kgs with same strength.
7	Supporting ‘H’ column Weight of 8 ft is just 108 Kgs being Hollow with same strength.	Supporting ‘H’ column Weight of 8 feet is just 116 Kgs
8	Labours requirement only 6 Nos.	Labours requirement minimum 20 Nos. + Supervisor
9	Moulds are not used, No limitation in production.	Moulds used & highly Labour oriented, hence Limitation in production.
10	Curing Time Very less as dry concrete is used. Cement Water ratio 0.3%.	Curing Time Very high as wet concrete is used.
11	Day & Night production possible by increasing 4 labours.	Day & Night production not possible as moulding cycle is of 24 hours.
12	Expansion - Using present set-up & Supporting Machine it is cheap & easy.	Expansion - Using present set-up & Supporting Machine it is very difficult.
13	Transportation cost is affordable for long distance as there is high margin	Transportation cost is not affordable for all above limitation.
14	Stocks - Low. Cut length from slab as per order & no wastage.	Stocks - High. Requires Mould for different length or cut from stock & waste
15	Hole in centre of column while Extruding to fix steel angle & Barbed wire.	Hole not possible for fix steel angle & Barbed wire.
16	Water - free of salt required for production is very less.	Water - free of salt required for production is More.
17	Monsoon it is Not difficult to manufacturing, just stop when it rains.	Monsoon it is Very difficult to manufacture most plant are closed.
18	Panel Size 50 x 300mm x 7 ft. long weighs only 9.5 Kgs. / ft. For making Wall of 6 feet Height and 7 feet long: - No of Panels on 7 feet required are 6 Nos. i.e. 66.5 x 6 = 399 kgs 'H’ Column of 8 feet long (13.5 kgs) – 1no is 13.5 x 8 = 108 kgs Total square feet are44 & Total weight Approx. 507 Kgs. Saving in weight - 40 kgs in just 44 Sq. ft.	Panel size 50 x 300 mm x 7 ft. long weighs 10.28 Kgs. / ft. For making Wall of 6 feet Height and 7 feet long: - No of Panels on 7 feet required are 6 Nos. i.e. 71.96 x 6 = 432 kgs ‘H’ Column of 8 feet long (13.5kgs) – 1no is 14.5 x 8 = 116 kgs Total square feet are 44 & Total weight Approx. 548 Kgs. More Weight – 40 Kgs. In just 44 Sq. Feet.
