FAQ

  • Erect your Steel Structure Building

    Our company, Qingdao Xinguangzheng Steel Structure Co., Ltd, specializes in the building of steel structures for factorieswarehouses and any other large building structure. 
    Steel is a metal alloy consisting of iron and carbon. Steel is utilized in a variety of construction fields to erect steel structures, cables, bolts, temporary props, as well as decking elements. It is common for steel structures to be galvanized using zinc; this helps to protect the steel structures against corrosion and rust. When erecting steel structures, different steel members are welded or bolted together in order to make permanent connections. It is also quite common for steel to be used in conjunction with concrete or timber when new steel structures are erected.
  • What Is Residential Steel Structure Construction

    Steel members are also used to construct the entire internal steel structure (frame) of a house through the use of a typical stud framing system. Steel studs are similar to timber studs in size and shape and are available in regular (rectangular) and open stud (square C shape) sections. This steel structure is galvanized to protect it against moisture. Steel structures are strong, durable, lightweight and non flammable, making it a great choice for fire-prone areas. Many steel members used in the erection of steel structures are fabricated with pre-drilled holes for ease of installation. This in turn saves time and money.
  • Advantage of prefabricated steel building--Reduced Construction Time

     Advantage of prefabricated steel building--Reduced Construction Time
    Due to the systems approach, the use of high strength steel, use of tapered built-up sections which are optimized by the computerized design program and the use of continuous light gage secondary steel section, there is an overall reduction in steel weight, cost and time relative to conventional steel construction.
    Prefabricated Steel Building are a predetermined inventory of raw materials that has proven over time to satisfy a wide range of structural and aesthetic requirements. The components are engineered beforehand and standardized. Use of these standard components reduces the engineering, production and erection time. Use of customized software for design & drafting increases the speed of the project.
    The production line is highly sophisticated, having Auto welders, multi-cutting torches, shear cutting machines etc., which greatly reduce the time of fabrication of built-up components. Roll forming machines for producing Z & C members and sheeting, having standard dimension, increases the production capacity of secondary members. Use of standard accessories greatly increases the speed of production & erection.
    Buildings are typically delivered in just a few weeks after approval of drawings. Foundation and Anchor Bolts are cast in parallel with manufacture of the building. Site assembly is fast, as all building components are delivered finished, ready for site bolting.
     
    It can reduce total construction time on a project by at least 50%. This will allow faster occupancy and earlier realization of revenue.

     Advantage of prefabricated steel building-Design

    Since prefabricated buildings are mainly formed of standard sections and connections, the design time is significantly reduced. Specialized computer analysis and design programs optimize material require. Drafting also computerized using standard details that minimizes project

    custom details. The low-weight flexible frames offer higher resistance to seismic forces.

      Quality Control:



    As buildings are manufactured completely in the factory under controlled conditions, the quality is assured.
      
      
      
      
      
     Low Maintenance:
    Buildings are supplied with high quality paint systems for cladding and steel to suit ambient conditions at site, which results in long durability and low maintenance costs.
     
  • Advantage of prefabricated steel building--Lower cost

    Advantage of prefabricated steel building--Lower cost
    Due to the systems' approach, there is a significant saving in designing, manufacturing and site erection cost. The structural components are shaped to follow the stress diagram of the member, thus reducing weight, cost and load to foundations. The secondary members and cladding nest together reducing transportation cost. The overall price per square meter may be reduced as much as 30% lower than conventional steel.
     
  • Reduce your cost to build your Commercial building

    Today the modern market place demands fast response and supply for everything from a storage rack to a steel building and from a clothes cabinet to a commercial building.
     
    To facilitate the construction sector commercial buildings are now supplied as sectional steel commercial buildings or rather as prefabricated sectional steel commercial buildings.The commercial building market has to respond to the changing requirements of the market such that after a severe downturn in the economy an upturn can be capitalised upon by offering swift commercial construction techniques.
     
    Costs are ever under pressure and prefabricated commercial steel buildings have the benefit of being manufacture in tightly controlled factory environments where manufacturing techniques can be tuned to offer the best material yield at the very highest levels of repeatability and accuracy.This means that steel building, including commercial steel buildings, can be supplied quickly and with the very highest levels of confidence in the manufacture of the steel components. This in turns reduces site construction costs and assists in completing the building time to schedule.

    Advantage of prefabricated steel building--Foundation and erection
     
    Foundations:
    Prefabricated Steel Building are about 30% lighter than the tranditional steel structures. Hence, the foundations are simple design, easy to construct and lighter weights.
    Erection:
    Since all the connections of the different components are standard, the erection time is faster.
     
  • Cost of structural steelwork

    Cost is a fundamental consideration in the chooseion of structural frame material and form, which is a key early decision in the design process. This chooseion should be based on project specific costings, and the challenge to the cost consultant is to recognise and reconcile fluctuations in material prices in relation to returned tender price data all in the context of limited available design information during early estimates.
     
    Low rise and short span buildings
     
    Low rise buildings with a regular, short span structural grid are typical features of business park offices and teaching facilities. A key feature of these buildings is flexibility, particularly for speculative business park developments that need to appeal to as many potential occupiers as possible.
    The buildings often need to be easily subdivided into smaller units and have large floorplates, typically are two to four storeys and have floor-to-floor heights of 3.75-4m. These buildings will typically have a uniform grid of 6-9m that provides largely column-free space and relatively high floor-to-floor heights.
    The lack of complex steel structures needed to construct the regular grid contributes to keeping the average steel frame weight down, typically 50-60kg/m2 including fittings, but this category can cover a lot of building types and functions. This central assumption therefore needs to be reviewed with the design team. Due to the low rise nature of these buildings, the fire protection requirements are not as onerous as for high rise developments and 30-60 minute fire protection would be considered standard.
     
    Industrial buildings
     
     
    Industrial buildings can cover a range of uses, including warehouses, non-food retail, science parks and distribution centres. The most common building form is a single storey warehouse with varying proportions of office space on a first floor mezzanine level. The traditional structural frame for an industrial building is a steel portal frame, as flexibility of the internal space is a priority, necessitating regular column spacings and long spans for a clear internal area.
    There can be variants on the standard frame design, however. For example, a steel portal frame incorporating northlights would need consideration when adjusting the standard cost ranges. The use of a northlight frame can increase the frame cost by as much as 30%.
    Fire protection requirements may also be considered as part of industrial building frame costs. The most common situation in which fire protection is required in single storey buildings is where it is necessary to satisfy boundary conditions; this is a project-specific factor that will need some liaison with the design team. Generally however, single storey buildings do not require fire protection.
    Another key factor in determining the frame cost of industrial buildings is the storey height of the warehouse space. While the gross internal floor area may be the same, the weight of the steel frame of a high eaves, single storey industrial building will be higher than for a low eaves building, resulting in a higher overall frame cost per m² GIFA.
    Typical structural steel frame weights for low eaves buildings (6-8m high) are about 30-40kg/m² overall of GIFA, including fittings and about 40-50kg/m² for high eaves buildings (10-13m high). However, ranges for high eaves buildings are generally wider than for low eaves buildings as they can have a much higher proportion of upper floor areas, across as many as 3 mezzanine levels; the frame rates for these buildings therefore need to be looked at carefully on an individual basis.
