WOHUA PHARMACEUTICALS industrial workshop
General Information
Surface Area: 7000Sq.m
Crane: 30 tons.
Size: 27.5 x 252 x 11m eave height
Steel Frame: Lattice column + light steel bracing
Wall and Roof Cladding: Separate Single PPGI Metal Sheet with White Colour
Application: to manufacture long circular tubes with size length 21m and diameter 2m
First stage, With the expanding of production capacity, two more same sizes prefabricated steel working halls constructed again requested by clients.
The structural form of this project is upper portal steel frame, lower steel frame, steel frame, beams and columns are all made of Q355B grade steel unless specified, channel steel, angle steel and round steel are all made of Q235B, and the welding seam requires the lower flange of the crane beam The requirements are Level 1, and other places require Level 2 and Level 3. Component painting requirements: all exposed iron buildings must be derusted, epoxy zinc-rich primer is applied 2 coats, epoxy mica intermediate paint 2 coats, fire-resistant paint is applied on site, and the service life is 15 years.
The light steel structure workshop in the project requires good heat insulation. Therefore, the roof tiles and exterior wall panels use color steel rock wool sandwich tiles, which greatly reduces the temperature in the workshop, and the staff can work more comfortably, while also being able to budget. Reasonable control. As for roof purlins, wall purlins, and floor decks, KXD engineers also recommend the use of galvanized C-shaped steel. Galvanized C-shaped steel refers to the use of high-strength steel plates, which are cold-formed and rolled to form a uniform wall thickness and excellent cross-sectional performance. , High strength, compared with traditional hot rolling, the same strength can save 30% of materials. Galvanized C-section steel has uniform zinc layer, smooth surface, strong adhesion, high dimensional accuracy, all surfaces are wrapped by zinc layer, long service life, corrosion resistance and durability, it is the strongest protective galvanized steel.
Our company used the fabricated steel structure in this light steel structure plant project, and carried out in-depth prefabrication in advance in the factory, meticulously to each connection position and bolt arrangement, saving construction time, on-site evaluation by a dedicated technical team, technical detailed inspection, The complicated connection of the steel structure prefabrication, many nodes, high design requirements, short installation time and other problems are eliminated, and all the production problems are completed efficiently.
We have sent different types of prefabricated steel buildings to South Africa via engineering contractors or consultants like portal frame steel warehouse, steel sheds, steel workshop, steel buildings and also temporary buildings like modular prefab container houses used for homes, hospitals, school. This building can use for agricultural field feedlot, dairy, machinery sheds, piggeries, shearing sheds, lambing, sheds, equine arenas, horse barns.

The construction of steel structure workshop (also called steel hall) is mainly divided into the following parts:
❶ Embedded parts to stabilize the structure of the complete plant
❷ Columns as primary steel members are generally H section welded steel coating with epoxy or alkyds paint for corrosion resistance
❸ For beams as primary steel members, generally H section welded steel are used. The height of the middle ridge is determined according to the span of the beam.
❹ Purlin as secondary steel members: C-shaped galvanized steel and Z-shaped galvanized steel are generally used.
❺ Supports and braces are usually round steel coating anti-corrosion paint.
❻ Roof and wall cladding system. The first one is a single separate tile (PPGI tile) without insulation layer. The second type is sandwich composite panel. Polyurethane, glass wool, rock wool and EPS are sandwiched between the two layers of color-coated metal sheet to play the role of warming in winter and cooling in summer, and also has the effect of sound insulation and fire prevention.
The main advantages of steel structure workshop are:
Light weight, high strength and large span:
Although the density of steel is higher than other building materials, its strength is very high. Under the same force, the steel structure has a small dead weight and can be made into a structure with a larger span.
Short construction time:
the structural parts of the plant are mainly produced in the factory and prefabricated, and then installed on the site. The erected work is convenient and the construction is convenient.
High fire resistance:
When the surface temperature of the steel is within 150℃, its strength changes little. When the temperature exceeds 150℃, its strength decreases significantly. Generally, fire retardant coatings are applied to the surface of steel structures to form a protective film to increase the fire resistance limit of the components. Of course, the reasonable division of fire compartments and the use of fire shutters are also very important.
Sound insulation and heat preservation:
Fill the metal roof with sound insulation material (usually glass wool, EPS, rock wool, polyurethane), or add heat insulation reflective paint on the metal tile surface.
