Product Presentation

Steel structure industrial buildings are widely used in industrial production, warehousing and logistics, etc. These buildings are mainly constructed with steel as the core structural material. They consist of components such as steel columns, steel beams, and steel trusses to form the load-bearing framework, along with cladding materials like color steel plates and sandwich panels.

The large-span design does not require excessive support from columns, making it convenient for the installation of large equipment, cargo handling, and vehicle passage.

Whether it is a mechanical manufacturing workshop accommodating heavy machinery, a logistics warehouse achieving high-shelf storage, or an aviation hangar for aircraft parking, they can efficiently meet the usage needs and provide a solid spatial carrier for industrial production and operation.

Product construction

Component composition: The framework is composed of steel columns, steel beams, and steel trusses. The roof and walls are made of lightweight enclosure materials (such as color steel sandwich panels). Most of the steel columns are H-shaped or box-shaped, providing vertical load-bearing capacity; steel beams are connected by welding or bolts, forming a horizontal load-bearing system, and trusses enhance the structural stability under large spans.

Industrialized construction: More than 90% of the components are prefabricated in factories, precisely cut, welded, and treated for corrosion prevention before being transported to the site. On-site construction mainly adopts "assemblage" methods, using high-strength bolts to connect steel components, significantly shortening the construction period. For example, a factory building of 10,000 square meters, from foundation to topping out, only takes 1-2 months, much faster than traditional concrete buildings.

Adaptive design: The foundation design is flexible. Independent foundations or pile foundations can be selected based on geological conditions. The structure has strong scalability, and adding floors or modifying spaces only requires adjusting the connections of steel components, meeting the needs of enterprises' capacity expansion and functional iteration.

Quality Standard And Control
With 20 year warranty in the steel building industry,our company has standard on the quality of steel building. We have acquired the ISO9001 and CE certificate. The followings are the related standard that we strictly follow whether for the design and fabrication of steel buildings:
GB/T1591-2008/2018
GB/T11263-2010
GB/T 2518-2008
GB/T12754-2006
GB/T 1228-2006
Here we take an example on the Process, fabrication and quality control standard on fillet weld size.
1. Purpose

To ensure the quality of fillet weld, meeting up the technical requirements of welded members and improve the standardization of our fabrication, we specially formulate this regulation.
2. Application scope
This manual is applying for the design, fabricate and inspection for the fillet weld size.
3. Fillet weld leg size:
3.1. Definition of fillet weld leg size(K):
Length of catheti from maximum isosceles triangle that drawn from the section of fillet welding seam

3.2. Fillet weld leg size requirements:

3.2.1. All the fillet weld size should not be less than the drawing and design values.
3.2.2. Minimum fillet weld size K≥1.5×,
3.2.3. Maximum fillet weld size K≤1.2t
3.2.4. When the fillet weld being on the edge of welding members(t), the fillet weld size cannot exceed the edge of the welding member and the maximum weld size is as followings:
1)when t≤6mm,K≤t;
2)when t>6mm,K≤t-(1~2)mm
3.2.5. For fillet weld size in circular holes or trench holes, K≤(1/3)d

3.2.6. For the fillet weld size without groove, it should not be more than 17mm.

3.2.7. For the fillet weld that requires CJP:K≥t/4, see photos of 3(a)(b)(c).
4. Selection of fillet weld size
Based on the standard and our experience and actual process, the requirements on the fillet weld size should be as followings(in terms of when there is no request on drawing but there is inspection request):

Form of fillet weld leg	K(fillet weld size) value	Note
Fillet weld without groove	K=(0.7~1)t and ≤15mm	for most of the steel structure buildings
Fillet weld without groove	K=(0.5~0.6)t	for the strengthening ribs and other secondary members
Fillet weld with groove(CJP and PJP)	K=t/4 and K≤10mm	for most of the steel structure buildings
Fillet weld with groove(CJP and PJP)	K=t/2 and K≤10mm	important members(crane beams or connection between web plates and flange plates of similar members)
