Engineered wood materials are manufactured products that utilize strands, particles, fibers, and veneers of wood to produce a range of different types of products. Readily available at lumber yards, these products are cut to length in the field, similar to dimensional lumber. The application of engineered wood products is also similar to that of dimensional lumber; however, each offers its own performance and manufacturing advantages. Engineered wood products also have some disadvantages in comparison to dimensional lumber. They have less fire resistant, require more energy to manufacture, have adhesives that can potentially release toxins into the environment, and are prone to moisture damage. Engineered wood products are often used as columns, beams, girders, joists, purlins, rafters, studs and bracing.

Wood framing, or 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.

This topic covers information related to the treatment of wood with preservatives used in construction. Preservatives can be added to wood to prevent the growth of mold and deter insects. Methods of preservation include vacuum or pressure treatment with chemicals such as arsenic, copper, chromium, or borate, in addition to others.

This topic covers information related to the treatment or preservation of wood materials used in construction. Wood treatment increases durability and resistance, protecting wood from fire, moisture deterioration and insect infestation. Several types of preservatives and process exist to treat wood.

This topic covers information related to wood, plastic, and composite fasteners that are used in construction. Fasteners can be a hardware device that mechanically joins materials or a liquid mixture that bonds materials together. Fasteners include nails, screws, bolts, metal connectors and adhesives.

This topic includes information related to decorative metal railings installed during construction. Decorative metal railings are custom, functional handrails and railings. As compared to traditional handrails and railings, decorative metal railings have added aesthetic appeal.

This topic includes information related to decorative metal stairs installed during construction. Decorative metal stairs are custom functional stairways commonly made from aluminum or steel. As compared to traditional metal stairs, decorative metal stairs have added aesthetic appeal.

Decorative metal can be defined as metal that provides architectural decoration but has no structural value. Metal can be formed into countless shapes while still retaining many advantageous properties. A wide variety of metals and alloys can be used, including aluminum, brass, steel, tin, silver, gold, and wrought iron. Examples of decorative metal uses are countless but include spiral staircases, guardrails, handrails, gates, decorative brackets, and cornices. For certain projects, designers may specify metals that will react to the elements, resulting in a modified surface appearance called a patina. Other projects may call for painting or factory finishing to protect the metal or add aesthetic detail.

Formed metal fabrications include column covers, metal panels, and other metal fabrications that are used in the building industry. Through a variety of different processes, most metals can be formed into virtually any shape. Metal forming processes include roll forming, stamping and brake forming. All processes begin with sheet metal of varying gauges – a higher gauge corresponds to a thinner sheet. Aluminum, stainless steel and galvanized steel are all common materials used to fabricate formed metal components.

Metal casting is the process in which metal is melted and poured into molds, where it is allowed to solidify. Metal casting is one of the world’s largest industries, with over 2000 metal casters producing 13 to 15 million tons of castings annually. Metal casting is often used for making complex shapes which would otherwise be difficult or more expensive to produce.

This topic includes information related to metal stair treads and nosings installed during construction. Metal stair treads and nosings are fabricated portions of a stairway used for foot traffic from floor to floor within a structure. Stair treads may be solid plate, bar or plank grating and are commonly made from aluminum or steel.

This topic includes information related to metal floor plates installed during construction. Metal floor plates are solid floor plates with rough surfaces, treads or small perforated holes. Metal floor plates are used to cover a void located in a floor or road paving where an open space presents a fall hazard.
