With the rapid development of urbanization, the scale of factories continues to expand, but with the soaring land prices and other problems, many old factories are in urgent need of expansion and renovation. In order to save construction costs, shorten construction periods, and extend building functions, steel structure renovation and expansion has become a popular way of building renovation. In fact, for factories that were originally steel structure factories, it is very simple compared to concrete buildings. It is also completely fine to copy the structure and appearance of existing factories.

The expansion of steel structure factories is generally divided into horizontal outward expansion and vertical upward expansion.

Horizontal expansion: If there is space for expansion in the factory area, expansion to the surrounding area without increasing the height of the floor is horizontal expansion. Horizontal expansion is relatively simple, and there is no need to design it specifically for expansion. Just copy the existing steel structure frame and anchor the additions on it.

Vertical expansion: Increasing the floor height or interlayer upward is vertical expansion. The premise of vertical expansion is that the existing building pile foundation is sufficient to support it. If the factory area cannot be expanded to the surrounding area, and the height and span of the original factory building are relatively large, vertical expansion can be considered.

Steel structure mezzanine, steel structure partition, steel structure ceiling addition, etc. are all longitudinal expansion.

Advantages of steel structure factory expansion:

1. Steel structure is conducive to spatial modeling design and construction, and it is easier to realize various design ideas. It is highly feasible and easy to construct, especially in renovation and expansion.
2. Steel structure expansion can shorten the construction period. Compared with the case of rebuilding the factory, factory expansion can save costs, increase production space, and the construction is environmentally friendly, and does not delay the production and processing of the original factory.
3. Steel structure is strong and durable, light in weight, easy to carry and construct, stable, and has good earthquake and wind resistance. Steel structure expansion is more cost-effective.

Issues to pay attention to during steel structure expansion construction:

1. Steel structure factory expansion cannot be added casually, and must be carried out when obtaining local building permits. At the same time, it is necessary to communicate with the original builder whether the current building is suitable for expansion requirements. It is best to design and expand through the original builder. Do not find someone to renovate and expand privately to prevent safety and quality problems.
2. The expansion of steel structure should take into account the current building situation. If the building is too old and has a short service life, it should be considered to be demolished and rebuilt. It is more appropriate to increase the building area or design it as a multi-story building when designing a new building.

Steel structure buildings often encounter expansion, and expansion is also a way to reduce costs. How to expand, expansion design must be consulted with a professional steel structure factory, ensuring safety is the first priority.
