Benefits of Structural Steel in Residential & Commercial Construction

Structural steel is widely used construction material for residential, commercial and industrial construction. Structural steel offers numerous benefits compared to conventional wood, timber or concrete made structures. It offers advantages like highest strength, fire resistance, speedy design and installation and less cost.

Structural steel is globally accepted and durable form of construction that can meet your specific building lifespan requirements. Steel columns are lean which results in larger floor area. Building foundation costs with structural steel is lower due to its excellent strength to weight ratio. The structural members can be fabricated offsite resulting in easy onsite implementations. Steel members can also be prefabricated as per design requirements to offer greater flexibility and easy accommodations of changes.

Steel's superb strength to weight quotient allows apparently economic use of floor area and space. Last few years have witnessed dramatic change in Computer based design (CAD) process and tools resulting in increased efficiency in steel design, fabrication and installation. There has been continuous improvement in CAD technology offering automatic updates of shop drawings when any of the design parameter is modified.

With steel construction, additional structural members can easily be accommodated and erection schedule can be modified on the fly. During the shop fabrication you can suggest many alterations as per requirements and those changes can readily be achieved with 3D modeling tools. It is also possible to release and remake steel connections at rapid pace with ease.

If you want to extend or alter the use of the structure (for example, accommodate more loads) then the structural members can easily be strengthened or extra beams or columns can be incorporated. Each steel frame can be designed, detailed using 3D models and linked to the CNC shop thus ensuring high dimensional accuracy and error-free connections.

Steel construction allows offsite fabrication of components. Other trades like mechanical or electrical can simultaneously carry out their work resulting in less delay at construction site.

Steel Building Construction

Steel building construction is the process of building a structure, using steel as the raw material. Steel is an advantageous building material that enables a simple and easy construction process. Steel building construction has 48% of the total market share of construction. It includes commercial buildings, industrial buildings, temporary shelters, storage units, churches and air hangers. The construction process differs with the style of the building. However, the basic steps are the same. Steel building construction is flexible than traditional building methods. Steel building construction is taken up by many architectural firms. It also provides the opportunity for do-it-yourself construction.

Planning and scheduling are the pre-requisites of steel building construction. The standard patterns include LRB, LR and LM. The design that suits the needs and purpose can be finalized from available patterns. In standard construction, the material fabrication is done at the site of the building under the supervision of the engineers, according to the custom design. Now, pre-engineered systems are available, in which 70% of the system fabrication is done in the manufacturer's factory and shipped to the construction site. The customer merely has to assemble the building kit on the ground. This reduces the labor and 2 or 3 people will be enough to erect this building.

The style of steel building construction is based on the space requirements. A building permit is essential to start the construction. The foundation is the basic step of onsite construction. Depending on the weather and soil conditions, an appropriate foundation lay out is selected. Concrete floor slabs or steel base rails have to be built. The main columns of the steel frame are embedded to the foundation. The building rafters are fixed to the columns with anchor bolts. The wall frames leave places for doors and windows. The roof sheet is installed on the purlins and wall girts with metal screws. Door and window installation is the final step in steel building construction. In case of arch construction, the arches that act as side walls as well as roofs can be erected from the foundation, one after the other. Insulation can be also added to the steel building.

Steel building construction offers benefits such as faster installation, sustainability and unlimited design flexibility. It reduces energy cost and the amount of waste material. It does not require any sophisticated tools for assembly. Steel constructions can successfully withstand natural pressures such as earthquakes, severe cold or hurricanes. New innovations in the color code and accessories will add to the aesthetics of steel building construction.

Dangers Using Wood Stair Cleats - New Stair Construction

I would imagine most people don't even know what it wood stair cleat is, in construction we have so many words that describe the same thing. A stair cleat is another word for a thread bracket. In other words it's the part of the stairway that connects the stair stringer to the stair step. These have been used for years and over time, most of them will develop the same problem.

Most wood stair cleats loosened up and create a safety hazard. If the stairs are located outside in extreme weather conditions, for example, if it rains or snows a lot, extremely humid humid weather, or extremely hot and dry temperatures, your staircase might not last that long, if it is or isn't maintained properly. It's not a bad idea to use steel or concrete for stairways in these climates.

If you're ever walking up a set of stairs with wood cleats and the stair steps feel a little loose or wiggly, make sure you examined the stair cleats for safety. It's not uncommon for someone to be walking up or down a set of wood stairs and having the stair step or tread giveaway because the wood cleats has loosened.

If the wood stair cleats are nailed to the stair stringer, the nails can loosen up, causing it to become loose, as you walk up and down the stairs applying pressure to the stair cleat, this will create movement in between the stair step and the stair stringer. This could cause the cleat to crack, break and separate the connection between the stair step in the stair stringer.

I would suggest using metal brackets instead of wood cleats. The metal brackets will not crack or disintegrate like some wood cleats. Stair building brackets of course can loosen up and should be maintained regularly.

If you decide to use wood stair cleats, I would suggest using screws instead of nails and drilling holes in the wood stair cleats, most of the time this will prevent cracking the cleat. Try to use a thicker material for the stair cleat, for example using a 2 x 4 with lag screws and washers would be better than using a 1 x 4 with nails.

If you're walking up a set of stairs and a stair step feels loose, contact the owner of the property and let them know, they have a problem with their staircase.

Structural Steel Detailing - Steel Drawings For Modern Construction

For any successive construction structural steel, detailing is a vital process. All type of buildings need assurance of building stability. To satisfy this purpose structural industry is widely using the steel detailing. Mainly it is tough to get building stability for mega structures but after the launching the detailing services it becomes easier and quicker. Many of the countries are facing natural disasters so international community of structural engineers have developed standard codes must be follow for any type of construction.

Building stability is depend upon the various connections between slabs, columns and beams. All the connection must be done accurately as reconstruction can make high cost and consumes more and more time. To reduce the complexity steel detailers are using latest software like AutoCAD and Xsteel. Detailers are generating various type of steel drawings like shop drawings, fabrication drawings and erection drawings. All the joints and connection details are evaluated accurately using the fabrication drawings. For the stability purpose loads and external forces must be calculated properly.

When the detailing process is going on erection drawings are used to identify where to place the manufactured steel member. It is more important as misplacement of steel member causes high risk for building. Shop drawing used to determine the requirements for manufacturing steel members. Both the drawings processes provide advanced planning for delivery, material staging and equipment selection to be used in construction. This provides faster completion approach for any kind of construction.

It is used in manufacturing of various steel members and used to evaluate the estimation. Using the detailing technique detailers calculate the requirement of material and provide the information to engineers. In the modern time cost must be maintained without wasting the material. This technique is not only limited for real estate industry but it widely used in ship building, marine and naval constructions.

All the applications used in detailing process are extremely useful and there are many detailers are available to assist you in proper way. According to the industry it assures building stability so it is the most important process must be completed with accuracy.
