Prefabricated Metal Frame Structure Construction Steel Building

Product information

Steel structure/metal building structure is a structure composed of steel, mainly including steel beams, steel columns, steel roof trusses, walls, roofs, etc. Similar to traditional buildings, there are also ordinary doors and windows. Bolted connections are commonly used between various components or parts. 

However, in some large-scale projects, such as multi-story buildings or long-span warehouses or workshops, the columns and beams need to be segmented because they are longer. In addition to screw connections, we also recommend that customers perform appropriate spot welding in the segmented areas of columns and beams after the steel structure is installed and adjusted to enhance safety.

Steel structure building with their strength, durability, versatility, lightweight, and simple construction, it is widely used in large factories, venues, super high-rise buildings, and other fields.

The project we display here is a 2 story steel structure building for Papua New Guinea. When the customer shared project pictures with us, we heard that he was satisfied with our products. His words "Thanks for making accurate structures..." encouraged us, making us keep on providing high-quality products and services to every customer.

In this project case, we can see the floor decks for the each floor and and the roof. Floor decks are commonly used in multi-story buildings and are often combined with other elements such as beams, columns, and concrete slabs to create a solid and durable flooring system. There are two type of floor deck we usually use:880 type and 600 type.

1)880 type:(open type floor deck)

2)600 type:(close type floor deck) 

The difference between the above two floor decks:

1.The closed-type floor deck is a flat surface, while the open-type floor deck is a corrugated surface, so the construction is more complicated.

2.Open-type floor decks seal the ports to prevent pouring concrete from leaking through the openings at the bottom of the slab, while close-type floor decks do not need to be sealed because the webs are closed.

3.The close-type floor deck completely reduces the amount of on-site steel bar production, reduces manpower input, and speeds up construction;

4.The amount of steel used in close-type floor decking is relatively larger than that of open-type floor decking, so the cost will be higher.

A complete steel building performance

In steel structure buildings, generally speaking, the standard weight of one square meter of steel structure is between 25 ~ 30 kg. The specific value is affected by the geographical location of the building, wind load, snow load, and other natural environmental factors, as well as the type and specification of the steel, thickness, and other factors.

When our customer gives us specific drawings with steel dimensions, we will help him review the weight of the steel based on this standard. If the customer's design is lower than this steel weight standard, we will remind our customer whether a double check is needed to ensure the stability and safety of the entire structure.

If need to upgrade the design, usually we will suggest they make some changes to the beams and columns WEB and FLANGE thickness is can not less than 6mm and use the appropriate beams and columns according to the loads and pass the calculation.

In today's life, steel structure buildings that combine steel structure frame and concrete blocks (or bricks) walls are very common, because the combination of the two gives people the impression of being strong, windproof, and more importantly, earthquake-resistant.

Steel building advantages:

Statistically speaking, steel is one of the most commonly used building materials in modern construction overall. Steel structures are used for almost every type of construction, including heavy industrial workshop, warehouse building, storage shed, multi-story residential buildings, high-rise shopping malls, large-span exhibition hall, airport terminals, poultry farm, grain barn, godown etc.

1)Fast construction:

All the steel structures have been manufactured in a processing workshop. It can be transported to the construction site for assembly by bolts making the steel construction more convenient and the building time shorter.

2)Flexibility in design to meet a variety of needs:

A steel building can cover space that is not only versatile but expandable. It can also be built combined with the existing building or directly on the original conventional (or traditional) building. It can be easily expanded or modified in the future to meet changing needs or requirements.

3)Reasonable cost:

The steel is lightweight, which could reduce the basic cost. The fast construction speed can be completed and put into operation in a short time. The overall economic benefits are much better than that of the concrete structure building.

4)Withstand extreme weather:

The steel structure building is lightweight and high strength, it has good overall rigidity and has strong deformability. It can withstand harsh weather and life and property can be effectively protected. Safety and reliability, good seismic and wind resistance, strong load capacity, and earthquake resistance can reach level 8..

5)Minimal maintenance

Steel is a durable and long-lasting material that is resistant to corrosion, rot, and pests. It does not require regular painting or sealing like other building materials. Additionally, steel is not prone to warping, cracking, or shrinking, which reduces the need for repairs or replacements. Overall, steel buildings can save time and costs in the long run.

Steel building techniques

Steel building techniques include structural design, fabrication, welding, assembly, and installation. That refers to the methods and processes used in the construction of steel buildings. Steel is a durable and robust material that can support large spans and heavy loads, making it suitable for a wide range of construction projects. Steel has strength, versatility, and cost-effectiveness, making it a reliable and long-lasting choice for various applications.

Steel structure various application

Steel buildings have various applications in construction, including commercial buildings, warehouses, industrial facilities, agricultural structures, sports arenas, and residential buildings. Steel's versatility allows it to be used in a wide range of projects, providing strength and durability in different settings.

Technical Parameters

FAQ:

1. What is the wind speed that the steel structure you designed can generally withstand?

If the customer has no special wind speed requirements, we usually quote the wind speed as 100~110 km/h. We can also design some special countries and regions, such as the Bahamas and Mauritius, where the wind speed reaches 250~280km/h, but the cost will be higher.

2. I need to build a steel structure warehouse but the only information I have is the floor area. Can you help us design it?

If the customer does not have formal drawings, we can help him design according to his floor area and functional uses, and recommend suitable materials according to his budget.

3. How high are your warehouses usually?

If it is a conventional warehouse without a crane and is simply used to store goods, we recommend that the customer build a 6m~8m warehouse, mainly based on considerations of building structure and economic benefits.

4. My warehouse needs a crane. In addition to the crane beam, can you provide a crane? If the length of the crane is greater than 12m, how can I arrange delivery?

For customers who need cranes, we can not only provide crane beams and corbels to support the crane on the steel structure. We can also help customers purchase motors. Because we have long-term cooperative relationships with crane suppliers. If the length of the crane is greater than 12m, the crane can be separated into two parts and connected with screws on site. For more stability, the connection port can also be welded appropriately.

5. I want the floor to be strong and stable, but I don’t want to lay the floor decking and pour cement. It’s very time-consuming to tie the steel bars. Do you have any good suggestions?

If you want the floor to be strong and durable, we still recommend that customers use the method of laying floor decking and pouring cement. If you find it troublesome to tie steel bars, we can use floor decking with steel bars. Just lay this floor decking and pull a steel bar horizontally. , it must be fixed and cement can be poured.
