STRUCTURAL STEEL
The Future of Structure

If you’re looking for the most cost-effective building type, it’s important to consider your potential long-term savings along with your initial investment in any shape of structure, let’s think about steel structure. What is steel structure?

If you’re looking for the most cost-effective building type, it’s important to consider your potential long-term savings along with your initial investment in any shape of structure, let’s think about steel structure. What is steel structure?

Steel structure is a metal structure which is made of structural steel* components connect with each other to carry loads and provide full rigidity. Because of the high strength grade of steel, this structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure.

In modern construction, steel structure is used for almost every type of structure including heavy industrial buildings, multi-storey buildings, equipment support systems, infrastructure, bridges, towers, airport terminals, etc.

*Structural steel is steel construction material, which fabricated with a specific shape and chemical composition to suit a project’s applicable specifications.

Depending on each project’s applicable specifications, the steel sections might have various shapes, sizes and gauges made by hot or cold rolling, others are made by welding together flat or bent plates. Common shapes include the I-beam, HSS, Channels, Angles and Plate.

Main structural types


• Frame structures: Beams and columns
• Grids structures: latticed structure or dome
• Prestressed structures
• Truss structures: Bar or truss members
• Arch structure
• Arch bridge
• Beam bridge
• Cable-stayed bridge
• Suspension bridge
• Truss bridge: truss members


DESIGN

The most outstanding feature about CFS comes from the optimal design solutions performed by highly experienced, and professional engineering team.

CFS bring to customer satisfaction and complete peace of mind about the quality of design, in accordance with the most stringent technical requirements weather and environment conditions.

CFS design team performs their work in three stages:


– Technical design: All of the architectural drawings and structural steel drawings are assessed to ensure safety on the bearing capacity, the load on demand use, environment, art, …
– Manufacturing design: complete and accurate details of each component, size, quantity, technical requirements, 3D shapes.
– Erection design: describe the layout of each component and the requirements, erection phase diagram.
All projects are designing and manufactured following the latest US & European standards.


ERECTION

Erection of pre-engineered buildings and steel structure is the last step in our building process that all the components from the previous steps come together.

General Rules

• Build column combing with purlins (if any), brace column together. Then, continue building rafters after adjusting column.
• Install the inside truss frames, and then proceed to erect the outside ones (according to the movement of truck crane – see the enclosed construction drawing)
• Begin erecting from the braced bay.
• Settle two construction frames at the braced position before placing new frame. This process is translated for the next frame.
• Have to have temporary brace during the erection process. Use purlins with the bracing cable to locate, and link all the rafter frames.
• Erect steel panel after adjusting rafter frame and straight purlin, clean up, and paint all scratches on the rafter and purlin.
• Use chalks or stretch attached wires to locate or mark axis positions in order to balance the steel panel when to complete the covering.
• Set foot on the bottom waves when walking on the roof. Steel panel may be crashed if stepping on the high waves, which can cause deformation or leaking.
• Do not walk on bright panels.
