Steel Z-Beam

Z-beam, also called a Z-section (or Zee Purlin in the US) is a design of beam that is shaped in a similar way to the letter Z. This is a common type of structural component, usually employed as a secondary strut or purlin within steel frames. These elements are typically roll formed and span across above the main steel frames, beneath the roof covering. Other types of steel beams or sections include C-sections (or channels) , I-sections, T-sections and L-sections.

Z purlins or zed purlins are horizontal beams that are designed to form the roof and wall joists of a building shell structure. They sit between the roofing sheets and the building, acting as a support for the sheet to ensure it is firmly attached and safely in place. Our Z purlins are most commonly used in agricultural and industrial buildings due to their extremely versatile and lightweight properties which make them easily adapted for use in a variety of different sized buildings.

Cold Formed Purlin System

Purlins can be continuous. They can be used as beams, columns, frames and supports of steel structures.

Z-type rigid section dimensions

Z-beam is a common cold-formed thin-walled steel, processed from hot-rolled (painted) and galvanized materials, with good bending resistance and convenient installation 

To meet your specific needs, Yunsheng manufactures Z-Beam in a wide range of thicknesses that can be made up to any length. We can also manufacture them undrilled or with any diameter pre-drilled hole according to your requirements. (Oval and round holes of any dimensions can be provided on request.) Click here to get in touch!

Z-Beam Advantages:

• Ability to span length

• Saving in Steel up to 40%

• Fast to erect and easy handling

• No side drilling/cutting required

• Assured dimensions and straightness

• Purlin erection is easier than others

• Saving in construction cost up to 30%

• High durability, versatility and uniform quality

• Low transportation cost due to reduced weight

• Close tolerances on sectional dimensions owing to process of cold roll forming

• Saving up to 35-40% in weight and 20% in cost when compared to hot rolled purlins

Z-Beam Application:

Z-shaped steel is widely used in various fields. First, in the construction industry, it is often used as support rods, trusses, beams and other structural parts, which can effectively bear the weight of the building itself and external loads.

Secondly, in bridge engineering, Z-shaped steel is also an indispensable material, which can be used to make bridge decks, bridge piers and other parts.

In addition, Z-shaped steel can also be used to make parts of mechanical equipment, automotive structural parts, etc.

Yunsheng offers a selection of purlins available in the form of both Z purlins and C sections. Z purlins are horizontal beams that are designed to form the roof and wall joists of a building shell structure. They sit between the roofing sheets and the building, acting as a support for the sheet. All to ensure it is firmly attached and safely in place. Supplied plain or punched, galvanised purlins are manufactured from high tensile steel for increased strength, reduced weight, and a long serviceable life.
