§1What this business is
Cement, sand, stone chips and stone dust are mixed in a concrete mixer and poured into steel moulds around a cage of MS bars. The moulds are shaken on a vibrating table, the frames are taken out and kept in curing tanks, and hinges and fixtures are fitted. The frames do not rot or attract termites, so housing boards, housing societies and builders use them for low-cost houses. The profile names IS 6523-1983 as the standard for the product.
Capacity: 600 door frames and 750 window frames, valued at ₹6.6 lakh, as printed in the profile.
§2Is it right for you?

§6Schemes & subsidies
A small manufacturing unit like this fits a PMEGP loan with subsidy, or a MUDRA loan. Ask the bank to work on today's prices, not the old profile figures.
§7Money
How the investment is worked out: The profile prints a total capital investment of ₹3.00 lakh. The lines shown are machinery and equipment ₹1.3 lakh and working capital for 3 months ₹1,50,000; the premises are rented.
Working capital: Working capital for 3 months is ₹1,50,000. Each month needs raw material ₹25,000, wages ₹15,000, power and water ₹2,500 and other expenses ₹3,000.
Year not printed on the MSME-DI profile and the prices look old — machinery, cement and steel will cost much more now.
§8Export potential
A heavy, low-value product sold locally; export is not practical.
§9Risks — where people fail
- Cracks and breakage from poor curing or handling
- Cement and steel price swings
- Slow payment by contractors
- Building work stops in the monsoon
