Prefab steel structure homes, are homes built primarily with precasted and welded steel frames in a factory before being shipped to the site for final assembly. With the attention to detail and efficiency that comes from refining a work process over the years in the factory comes a number of environmental and economic benefits. Here are seven benefits of prefab homes.

1. LESS WASTE
    One-quarter of all non-industrial waste in the housing program is generated by the construction and demolition industry. As manufacturing processes are developed over time, pre-built home builders develop greater efficiency in their production and can more accurately gauge how much material is required for a job, resulting in less waste. Since materials are stored in the factory it also means leftovers are more likely to be kept and reused. Materials are also less likely to get stolen, vandalized, or damaged, something that tends to happen on construction sites and less so in factories.
Pre-built homes, however, do require more material in their construction than non-prebuilt homes because they have to be reinforced for delivery to the site. How much extra depends on how efficient the pre-built home is, but generally falls in the 10 to 30 percent range. When looking at all the factors that cause loss of materials on a job site—theft, vandalism, water damage, rust or just tossed away—and taking into account that the extra materials used for reinforcement make the home more durable, it makes more sense for the extra materials to be attached to the home rather than lying around on a job site.
2. DURABLE
    As previously mentioned, the extra materials used to reinforce the house frame for shipment make the home more durable. Being built in a factory, pre-built homes are also precision engineered, which contributes to their greater durability. 
3. SHORTER CONSTRUCTION TIME
     Prefab homes can be constructed in less time. Rather than having to wait for deconstruction of previous buildings and laying of foundation before building, a pre-built home can be made in the factory at the same time that those processes are happening. Since most of the building is done indoors weather delays are not an issue the way they are with stick-built homes.
4. BETTER FOR THE ENVIRONMENT
    Since most parts of the prfab homes are made in factory, it will requires less on-site construction, thus reducing noise pollution and materials wastes, disturb the site less than conventional construction, making the site clean and clear, and resulting in less CO2 emissions. workers will need only to erect and fasten parts and accessories with modern tools, mostly are pneumatically or electrically powered, which are faster and safer to operate with.
