Steel Stucture Description:

Steel structure load-bearing:
The frame load-bearing structure is a load-bearing system composed of a horizontal frame and a longitudinal connecting member, and the wall only serves as an enclosure. It is suitable for large spans, high plants, and large crane loads. The load-bearing framework is made of steel plate or hot-rolled steel through cutting and welding.

The horizontal framework of the factory building includes roof beams (or roof truss), columns, and foundations. It bears the loads from skylights, roofs, walls, and other parts, as well as its weight, various loads generated by cranes, and longitudinal wall wind loads. These loads are transmitted to the foundation through the transverse framework through the columns.

The longitudinal connecting components are connected by the roof purlins, wall beams, tie rods, supports, etc. to the horizontal frame to form a single-story industrial building space system. They are mainly to ensure the stability of the transverse framework, bear the tension load, and transmit it to the foundation through the column.

KXD Design Ability:

KXD Production Line:

In the production and construction process of steel structure buildings, modern process equipment is the core support for us to achieve efficient and high-quality delivery of projects. The automated cutting equipment is equipped with a CNC system with a cutting accuracy of ±0.5mm, which can accurately cut various types of steel to meet the needs of complex components and reduce material waste; the intelligent welding robot is equipped with intelligent sensing technology, and the welding speed is 3-5 times faster than manual work. The quality of the welds far exceeds the industry standard and can operate stably in harsh environments; the digital coating production line uses automated spraying equipment to accurately control the thickness and uniformity of the coating. The closed environment operation is both environmentally friendly and can improve the anti-corrosion performance of the steel structure by 5-10 years; the large crawler crane at the construction site has a maximum lifting capacity of 1,000 tons, and cooperates with the intelligent control system to ensure accurate and correct component installation.

Prepare raw materials : cut steel plate or use H section steel and angle steel,round tube,round steel,square tube etc. with right sizes;

Assembly and welding: our welders will follow the drawings to assemble the steel members and weld them together as a entire beam/column/brace and so on.
Our welders are skilled in butt weld,fillet weld,intermittent welding etc. The welding lines are straight,orderly and nice.
Our quality inspector will check the steel pieces after finish welding,this is the first quality check.

Sand blast : After finish welding and polishing,our sand blast effect can reach 2.5 high grade,very good for resist rust. 2.5 high grade could meet most countries' standard requirements.
(Secondary quality check)

Paint : Within 2 hours after sand blast,all the steel members should be paint. Client can choose any color and any brand of paint.
We use high pressure airless spraying machine for painting. Both the color and the thickness of paint are well-proportioned.
(The third quality check)

Inspect the goods by client : After we finish a part of fabrication work,we will invite clients to check the goods before we pack the steel frame.

KXD Packing and Loading:

If clients require us to load the goods by close containers,we will pack the steel structure members one by one on the steel skid and tie the whole steel package well.
For loading containers, there are different containers for different demands, like 20'GP, 40'HC, 40'OT.

Open top container:
Advantage:easy to load the steel; save steel pallet cost
Disadvantage:high shipping cost,aleak and few quantity to load

Closed container:
Advantage:save shipping cost,all members be packed together and reduce friction,the surface coating of steel members will be much better protected; easy unload
Disadvantage:steel pallet cost

Steel Structure Building Installation steps:

1.Foundation construction (pre-embedded anchor bolts),

Installing detailed drawing will be offered in advance.

2. Column installation

One worker commands truck crane how to move, 3 ~ 4 workers cooperate with crane to install the steel column, put column to anchor bolt location.

3.Beam installation

After completing the installation of adjacent two steel column, then main beam begin to install.

4.Installing roof & wall purlin

The roof and wall purlin will be installed after finishing column and beam. Bolting the purlin on the main structure.

5.Fixing wall and roof sheet

To fix the wall sheet on wall purlin by self-tapping screw; then fix the roof sheet.

6.Fixing the cover

To install the cover on the corner, eave, window and door opening.

7.Install windows and doors.
