Commercial Buildings

Commercial Building

Commercial building refers to buildings for commodity exchange and business activities. Steel structure widely used in commercial and service buildings, such as office building, stadium, aircraft hangar, garage building, and low- and multi-story residential buildings.

It can also use for adding floors, rebuilding, strengthening the old houses, and the area that inconvenient transportation, tight construction periods, and portable demolition buildings.

Steel structure can also replace masonry or wood structure, which is recyclable, in line with environmental protection and sustainable development principles.

Commonly used steel structure load-bearing systems include steel frame structure, multi-layer frame structure.

The amount of steel used for light steel structure is generally 20 ~ 50kg / m2, which mainly depends on the structure type, span, column distance, live load, and size.

The steel structure characterized by the use of a portal-type rigid frame as the main load-bearing structure, and the enclosed uses the corrugated color coated metal sheet, which is widely used and has a variety of stereotyped complete sets of operations. The reasonable span is generally between 18 ~ 36m.

The steel frame has various types of structures, which can be single-ridge, multi-ridge, single-span, multi-span, high-low span, or single-slope, double-slope, and flat-slope. Most of the components are I-shaped sections, and equal parts and variable sections can use.

A typical structural system is mainly composed of a foundation, a main rigid frame, the wall beam, purlin, wall and roof cladding, the wind-resistant column, roof support, and inter-pillar support.

Advantages of Steel Structure Commercial Buildings :

1. Structural design, detailed design, computer simulation installation, factory manufacturing, site installation, which are performed simultaneously with a small time difference.

2. It adopts a high-efficiency and light-weight thin-walled profile, with lightweight, high strength, and small occupied area.

3. The structural parts are all automated, continuous, and high-precision production, and the product specifications are serialized, shaped, and matched. The dimensions of each element are accurate.

4. The new wall material has a wide range of applications, a large number of lighting belts use, and the ventilation conditions are right.

5. The indoor plumbing electrical pipelines are all concealed in the wall and between floors, with flexible layout and easy modification.

6. There is no wet work in the dry method above the foundation, and the interior decoration is easy to be in place at one time. After galvanizing and coating, the profiles have a beautiful appearance and anti-corrosion, which helps reduce the cost of enclosure and decoration.

7. The house can relocate, and all materials can be recycled, which will not cause garbage and is in line with the sustainable development strategy.

8. It is convenient to expand the column distance and provide more separation space, which can reduce the floor height and increase the building area (the practical residential area can reach 92%). It has distinct advantages in layer addition, transformation, and reinforcement.
