Light weight Steel Framing:
Steel has been in use for over 100 years in the North American Construction market. While it is often associated with skyscrapers and bridges, steel is emerging as the material of choice for industrial, commercial and institutional (ICI) buildings. Lightweight steel framing (LSF) is an increasing popular choice in low to medium rise structures such as schools, shopping malls, box stores, stacked row houses, hotels, assisted care residencies and office buildings. LSF is used in the wall, floor and roof assemblies in buildings from one to six stories in height. LSF alone can provide all necessary structural elements or it can be used in combination with other materials for greater building diversity and scope
light frame construction, is the assembly of dimensional lumber or engineered wood lumber that is regularly spaced and fastened together with nails to create floor, wall and roof assemblies. Wood is the most common material used within the construction industry today.
Floor, wall, roof and stair assemblies are each made up of specific dimensional wood components, similar to a skeleton. These components are fastened together to form the structure and allow the interior spaces to function as desired. The following list identifies and describes each component within each type of assembly.
Structural Steel Framing:
which includes structural stainless steel framing, describes the creation of a steel skeleton made up of vertical columns and horizontal beams. This skeleton provides the support for the roof, floors and walls of the structure. There are three main types of structural steel framing systems. They are the clear-span rigid frame structure, the modular structural frame and single slope frame style. Choosing which type of steel frame to use for a given project requires the consideration of a number of factors, including building width, height, location, roofing type, and building use.
Sometimes an exterior wall’s structure provides the decorative finish, but most require extra material for decorative or weatherproofing purposes. For example, a brick or stone wall provides structure and finish, but a wood frame or block wall needs to be stuccoed or covered in siding. For most homeowners, the systems and techniques for these coverings become relevant only when they are faced with repairs. You will need to understand how these coverings are created if you want to match them on an extension, or if you wish to refurbish an entire section.
Choosing the right exterior cladding material depends on your climate, personal preference, and budget. Follow all manufacturer’s guidelines and local codes to ensure the material you choose performs well over time. One part of this is choosing the correct fasteners for the material and your weather conditions. Most often, you will need to use rust-resistant nails for exterior work.
Interior finishes and space-division systems define the living spaces within residential buildings with a range of both natural and synthetic materials. The most widely used wall finish is gypsum board, a prefabricated form of traditional wet plaster. Wet gypsum plaster is cast between paper facings to form large panels that are nailed to light timber or metal frameworks. The joints between the panels are filled with a hard-setting resin compound, giving a smooth seamless surface that has considerable fire resistance. Gypsum board forms the substrate to which a number of other materials, including thin wood-veneered plywood and vinyl fabrics, can be applied with adhesives. In wet areas such as kitchens and bathrooms, water-resistant gypsum board is used, sometimes with the addition of adhesive-applied ceramic tile.

Custom Steel Metal Fabricator:
Metal fabrication is the building of metal structures by cutting, bending, and assembling processes.
- Cutting is done by sawing, shearing, or chiseling (all with manual and powered variants); torching with hand-held torches (such as oxy-fuel torches or plasma torches)
- Bending is done by hammering (manual or powered) or via press brakes and similar tools. Modern metal fabricators utilize press brakes to either coin or air-bend metal sheet into form.
- Assembling (joining of the pieces) is done by welding, binding with adhesives, riveting, threaded fasteners, or even yet more bending in the form of a crimped seam. Structural steel and sheet metal are the usual starting materials for fabrication, along with the welding wire, flux, and fasteners that will join the cut pieces. As with other manufacturing processes, both human labor and automationare commonly used. The product resulting from fabrication may be called a fabrication. Shops that specialize in this type of metal work are called fab shops. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication.
Fabrication comprises or overlaps with various metalworking specialties:
- Fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on metal preparation and assembly as described above. By comparison, machine shops also cut metal, but they are more concerned with the machining of parts on machine tools. Firms that encompass both fab work and machining are also common.
- Blacksmithing has always involved fabrication, although it was not always called by that name.
- The products produced by welders, which are often referred to as weldments, are an example of fabrication.
- Boilermakers originally specialized in boilers, leading to their trade’s name, but the term as used today has a broader meaning.
- Similarly, millwrights originally specialized in setting up grain mills and saw mills, but today they may be called upon for a broad range of fabrication work.
- Ironworkers, also known as steel erectors, also engage in fabrication. Often the fabrications for structural work begin as prefabricated segments in a fab shop, then are moved to the site by truck, rail, or barge, and finally are installed by erectors.
