Distance between columns, across the width of the building. A clear span building has no internal supports, making the entire space under the roof useable.
The weight of additional permanent materials other than the building system, such as sprinklers, mechanical and electrical systems, partitions, or ceilings.
Vertical support member for primary or secondary framing system.
The displacement of a structural member or system under load.
Design loads are the forces to which the building will be subjected. Required design loads must be specified at time of quotation. Loads are applied in accordance with the latest building codes and standards applicable to steel building systems.
The line along the top of the sidewall, formed by the intersection of the roof and wall panels.
The lap of two separate roof panels as they provide coverage down the slope of a roof. An endlap occurs when a roof width is greater than the available length of roof panels.
The on-site assembly of a steel building system (pre-engineered building) or components to form a complete structure.
A party who assembles or erects a steel building system.
A break or space in construction to allow for thermal expansion and contraction of the materials used in the structures.
Fasteners are clips or screws used to attach panels to the structure and to each other. A typical fastener is self-drilling and self-tapping. Exterior fasteners are colour matched to the panel, so they blend in nicely.
The projecting edge of a structural member.
The system used to seal membrane edgings at walls, expansion joints, drains, gravel stops and other places where the membrane, cap or counter flashing shields the upper edges of the base flashings.
A typical coating weight for galvanized steel sheet. Equates to .090 oz. of zinc per square foot, total both sides.
A triangular portion of the endwall of a building, directly under the sloping roof and above the eave height line. The point at which an endwall meets a roof plane.
A secondary horizontal structural member attached to sidewalls or endwall columns to which wall covering is attached and supported horizontally; usually a cold-formed “Zee” shape.
Gutters are the trough that channels water from the eaves to the downspouts.
The area of increased depth of the column or rafter member, which is designed to account for the higher bending moments that occur at such places. Typically, this occurs at the rafter-to-column connection.
The horizontal structural member located at the top of a framed opening.
Any material used in building construction to reduce heat transfer.
A structure having only one slope and depending upon another structure for partial support.
The direction parallel to the ridge or sidewall of a building. Commonly, the direction referred to as the building length.
A party who designs and fabricates a steel building system. The manufacturer converts raw material into finished steel building system components.
An engineer employed by a manufacturer who is in responsible charge of the structural design of a steel building system fabricated by the manufacturer.
Same as steel building system or pre-engineered steel building. All three terms are used to describe the same product.
An intermediate level between floor and ceiling occupying a partial area of the floor space.
The regular undulations or waves that can form in large flat surfaces of thin material.
Steel panels (cladding) act as the skin of the building. Panels cover the walls and roof of your steel building.
The uppermost point of a gable.
A number given to each separate part of the building for identification. Also called a mark number and part number.
An inclination or slope measured in degrees, or percent, or by the ratio of the rise and run.
The accumulation of water at low or irregular roof areas; also used to refer to the progressive accumulation of water from roof deflection due to rain loads.
A structural framing system utilized at the endwall which is composed of corner post, end post and rake beams. These frames are used when a building will never be expanded in that direction.
Terminology previously used to describe steel building systems (metal building systems). This terminology was used when rigid frames were ‘pre-engineered’ for a desired load. Today, steel building systems are custom engineered to meet the size and design loads to meet the customers’ needs.
A secondary, cold formed horizontal structural member located in the roof to support sheeting, that is itself supported by the primary structure framing.
A fabricated primary structural member, that extends from the haunch member to the frame ridge. Any beam, in general, used in a primary frame to support the purlins.
Reactions are forces required to resist loads from a structure.
A raised line in the flat portion of a metal panel (cladding or siding) that gives added strength and minimizes the appearance of oil canning.
The highest point on the roof of the building, which describes a horizontal line running the length of the building.
Rods are utilized in conjunction with purlins and girts to form a truss-type bracing system located in both roof and wall planes.
The forming of metal shapes by applying pressure through rollers.
A roof secondary member, which is secured to frame rafters and supports the roof covering.
This is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/12 and 1/12. Any practical roof slope is possible.
The exterior roof surface consisting of panels, closures and attachments.
Concealed fastener roof, Steelway’s trapezoidal standing seam system.
A cold formed section is a structural shape that is formed by bending thin gauge (typically 10-16 gauge.) material at ambient temperature. A cold formed section is typically manufactured on our roll formers.
An exterior wall, which is parallel to the ridge and sidewall of the building.
A precise statement of a set of requirements, to be satisfied by a material, product, system or service. It is desirable that the requirements, together with their limits, should be expressed numerically in appropriate units.
Seam type that consists of an unturned rib that may also be structural, with a watertight seam. It is made by turning up the edges of two adjacent metal panels (cladding or siding) and then folding them over in one of a variety of ways.
Means a building system (metal building system or pre-engineered steel building), intended primarily for commercial, industrial, recreational or institutional occupancies, featuring steel structural and cladding components in conjunction with applicable appurtenances. Components are engineered to facilitate mass production and assembly in various combinations.
A built-up beam section, forming an ‘I’ shape, that consists of two flanges and one web. Using three-plate over conventional structural shapes allows for greater strength at a reduced weight. These sections are often tapered to optimize performance.
The light gauge metal used in the finish of a building, especially around openings and at intersections of surfaces, often referred to as flashing.
A continuous membrane in a building enclosure (i.e. wall or roof assembly) designed to prevent the migration of moisture from inside the building out through the enclosure. In an insulated assembly the control of moisture is important to stop condensation from building up in the wall or roof cavity.
A horizontal wall secondary member, usually a zee shape, which is secured to columns and supports the wall covering.
The exterior wall surface consisting of panels, closures and attachments.
Normally zinc oxide or aluminum oxide formed as the result of Galvalume® weathering; it is this property of Galvalume® which helps to protect the steel substrate beneath.
