Hindustan Prefab Limited (HPL) was incorporated in 1953. It was earlier founded as Hindustan Housing Factory Ltd., which was set up at the behest of Pandit Jawaharlal Nehru, the first Prime Minister of India for solving the housing problem created due to influx of refugees from West Pakistan. As years rolled by, the company came to be known as HPL, the change in name being necessitated by diversification of its operations. HPL thus became a fully integrated company with modern prefabrication facilities and a railway siding of its own in the heart of Delhi to undertake faster and challenging jobs in the country.

In the last 50 years of its existence, HPL has built a wide spectrum of civil engineering structures and has also supplied components for the building industry and the national railways. It pioneered the production of prestressed concrete railway sleepers which replaced wooden sleepers in Indian Railways. It also became the first company to produce precast pre-stressed concrete railway bridge girders for making railway bridges in the country. The company has built a large number of residential, factory and institutional structures, using precast concrete and prefabrication techniques.

Cities like Delhi are dotted with HPL structures and one of the landmarks in Delhi, the flagship hotel of the Oberoi Group was built on a precast concrete frame manufactured by HPL in its factory. Most of the other structures including over-bridges, factories, offices and houses were built by the company in record times and replaced the out-classed traditional cast-in-situ buildings.

HPL has a modern factory in Jangpura, on its 28 acres factory premises, virtually in the heart of New Delhi. The factory has five specific departments as mentioned below:

1. C-I Deptt. for manufacturing railway sleepers and electric poles.
2. C-II Deptt. for manufacturing railway sleepers and pre-stressed bridge girders.
3. Vayutan Deptt. for manufacturing autoclaved aerated cellular concrete.
4. RCC Deptt. for manufacturing reinforced concrete products like fencing posts, water tanks, pavement slabs, kerb
stones, Interlocking Solid blocks for pavements and for retaining walls, etc.
5. Wood work Deptt. for manufacturing door and window shutters from wood as well as from new materials like MDF (medium density fibreboard).

The above Departments are supported by steam generating boilers, batching plants, grinding mills, sophisticated handling equipments and above all a dedicated work force.

The company also has a very well equiped material testing laboratory in its premises. The laboratory has equipments for testing all the ingredients for manufacturing of concrete as well as the machines required for the testing of large and heavy concrete products, such as railway sleepers, electric poles and bridge girders. The laboratory enjoys a good reputation, and even out side agencies avail of its services, before they accept any raw materials from their suppliers.

The factory is pollution free and is one of the ecological oasis of Delhi with trees, water ponds, gardens and greenery.
There is a private railway siding inside the factory and the heaviest of products can be loaded into railway wagons for shipment to sites. HPL has a dedicated team of 500 employees which has 80 Engineers and other technocrats. The team work brings results & HPL has achieved many firsts in civil engineering construction techniques, earning awards from home & abroad.
