A:

Q1: Can I have a visit to your factory before the order?
A: Why not? Welcome to visit our factory. You can fly to Shanghai Pudong Intentional Airport then come to Xuzhou East railway station through high speed train about 3 hours , then we will pick you up at the railway station, hotel booking service is available.

Q2: Do you supply installation service?
A: Yes, we do. But you will pay for our professional installation cost in advance in accordance with the payment term confirmed by both of us, then we will send the engineers and construction workers to supervise it.

Q3: How long can the frame be used?
A: The use life of the main structure is the designed used life, usually is at least 50 years (standard request by GB standard)

Q4: How long is the use life of the roof cover?
A: The use life of the PE coating is usually 10-25 years. The use life of roof sun light FRP sheet is shorter, usually 8-15 years.

Q5: What is the anti-rust treatment for steel structure?
A: Anti-rust treatment of steel structure,

Normal anti-rust paint,
Anti-rust paint with epoxy zinc primer,
Hot-dip galvanization,
Hop-dip galvanization + PU finish,
Powder coating,
Stainless steel structure: No. 301/304/316 stainless steel structure.

Q6: How do we cooperate on certain project?
A: Firstly, please send us your project details and your requirements. Then we will design accordingly, free of charge.
Afterwards, please check and confirm whether you like the drawings. If not, we shall get the drawings revised until your confirmation.

Finally we make a deal.

Q:

What Should Be Included In The Design Drawing of Steel Space Frame Construction

+ -

A:

The steel space frame structure has good snow and wind resistance, excellent earthquake resistance, large span, large column spacing, convenient transportation and installation, short construction period, energy saving and environmental protection, and mostly job of the project is completed in the factory, which means the steel space frame structure is a green building. For this reason, mostly of our clients want to make the construction with space frame, cause it can help them save time and money.

When we start to co-operate with the manufacture, the first thing we need is the drawing design. That’s the beginning and the most important step. So we must know what should be included in the grid structure design drawings?

A complete design drawing of the steel space frame structure should include design instructions, space frame plan, space frame upper and bottom chord and webbing arrangement, detailed drawing of support seat and support, material table of rod parts, material table of bolt ball, material table of bolt, sleeve and top wire, material table of seal plate and taper head, detailed drawing of bolt ball processing (if other requirements are added, such as hanging parts, ventilator room, etc.)

When a design includes all contents, it’s a mature plan. Which means we can move our step on.

  1. Design code/ design standard
  2. Column position
  3. Maximum wind speed
  4. Seismic load
  5. Maximum snow speed
  6. Maximum rainfall

Q:

What is a space frame structural system?

+ -

A:

In architecture and structural engineering, a space frame or space structure (3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports.

Q:

How could a space truss be useful?

+ -

A:

Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut.

Q:

What are long span structures?

+ -

A:

Long span roofs are generally defined as those that exceed 12m in span. Long span roofs can create flexible, column-free internal spaces and can reduce substructure costs and construction times

Q:

How do space frames work?

+ -

A:

Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut.

Q:

What makes a frame structure?

+ -

A:

A framed structure in any material is one that is made stable by a skeleton that is able to stand by itself as a rigid structure without depending on floors or walls to resist deformation. … Each upper story is laid on crossbeams that are supported on the exterior wall by horizontal members.
