Beams And Girders

Our offered Product range includes C Purlins, Z Purlins and Z Purlin.

C Purlins

C Purlins

  • Width/Height/Depth 70mm – 600mm
  • Thickness 1.0mm – 3.0mm
  • Flange 40mm – 150 mm

DANA purlinmaterials are with a light weight in order to confer to an effective and faster construction work. The C purlins are worth mentioning in this regard as they provide the best resistivity against rust and can be degraded with much ease. The C purlins are used for the framing of exterior portions of the wall. It is their alluring look for which they are being used as wall posts on large scale.

With our capacity to deliver huge quantities of purlins and cold-roll formed sections with very short lead times, DANA Steel is a leading supplier to construction projects in UAE , neighboring gulf countries (Qatar, Oman, Bahrain, Saudi Arabia, Jordan, Kuwait) and African sub-continent.Our Purlins and cold-roll formed sections find application in a wide range of steel constructions, ranging from simple storage sheds to complex turbo-generator buildings in power plants.

Our Purlins have several advantages over conventional hot rolled sections:-
  • Light weight sections put minimal load on other structures / supports / foundations
  • Being factory-finished, they minimize wastage and installation time
  • Optimum sections meet exact design specifications
  • Very high strength to weight ratio
  • Cold forming increases yield strength and safety
  • Being supplied in a pre-punched condition and cut to sizes, DANA Steels Purlins facilitate easy erection and minimize wastage / rework at the site
  • Being painted / galvanized, they are maintenance free
DANA Steels Clientele Include Infrastructure Majors In The Fields Of:-
  • Power
  • Cement
  • Airport
  • Steel
  • Metallurgical
  • Automobile
  • Textile Sectors

Lengths:purlins and girts are supplied cut to required lengths up to 12m. Lengths exceeding this can be supplied but are subjected to suitable transport and site handling arrangements

Fastening:Fastening of purlins and girts to cleats in normally by either M12 or M16 class 4.6 bolts.

Ordering Notation :-

202c15 ( 202mm depth and 1.5mm thikness)

The first three digits of section reference indicate the depth of the section in millimeters (ie: 202 equals 202mm depth). The fourth digit is a letter that signifies the profile type(i.e: Z for Z profile & C for C profile). The last two digits indicate the material thickness ( i.e: 25 equals 2.5mm).

  • Specification :-
  • ASTM A653 Grade 50/80 G90 (New ASTM Standard, Min Yield Strength 340Mpa for Grade 50, and 550 Mpa for Grade 80)
  • ASTM A446 Grade D G90 (Old ASTM Standard, Min Yield Strength 340Mpa)
  • EN 10147 S350GD Z275 MAC

Z Purlins

Z Purlins

Dana Steel UAEs facilities are well equipped for producing Z- Purlins which are the secondary structural members used to support the roof sheeting and the wall cladding. Besides being economical to use, the Z-Purlins provide excellent strength to weight ratio. The Z Channels are manufactured from galvanized coils conforming to ASTM A 653, Grade D with minimum yield strength of 345 Mpa. We can also manufacture Z purlins as per ASTM A653 Gr. 80.The range of purlins produced by Dana varies in depth from 100mm to 450 mm and the related thickness varies up to 3mm thereby allowing them to cater to large spans of up to 12.0 m. The flange widths, lip sizes and flange angles of the sections can be set to be manufactured based on individual client needs. The same is true of the anti-sag rods and connection fasteners as well as the Z Channels which are customized in size to provide flexibility of the connection to the main structure whether by utilizing the overlapped system or the sleeved system.

Z Purlins manufactured by our factory are exported to All neighboring gulf countries like UAE, QATAR, OMAN, BAHRAIN, SAUDI ARABIA, KUWAIT, JORDAN and AFRICA(KENYA, TANZANIA, SOUTH AFRICA, DJIBOUTI, ETHIOPIA).
