DURA^® Portal Frame System (PFS) is a newly invented system for the construction of warehouse/factory using the revolutionary composite material of ultra-high performance concrete and high-carbon-high-tensile steel fibres (UHPdC). It is an excellent solution for long span warehouse/factory which consists of overall width ranging 120 ~ 260 ft and each frame is spaces 30 ~ 40 ft apart.

Features

• DURA^® PFS compose of two major structural elements being the prestressed Dura^® X650 Beam/Column and Dura^® Connector.
• Dura^® X650 Beam/Column are typically prestress to 70~80% of the ‘guaranteed’ tensile strength of the strands. Strands used are 15.2 mm diameter 7-wire super strands (low relaxation) complying with AS 1311; with a guaranteed tensile load of 250 kN and ultimate breaking load of 270 kN.
• The UHPdC used for the DURA^® X650 Beam/Column and Dura^® Connector has a cylinder compressive strength range between 120 to 140 MPa (equivalent to cube compressive strength of 130 to 160 MPa), and modulus of rupture over 15 MPa.
• DURA^® X650 beam/column eliminate the used of conventional steel reinforcing bars and stirrups. All steel fibres used are made from high carbon steel wires with tensile strength of 2300 MPa.
  

• DURA^® PFS are highly durable and impermeable. It is therefore suitable for use even in harsh environments.
• The construction sequence and method of DURA^® PFS is similar to the conventional steel portal frame system where bolt & nut is used to connect the members.
• No scaffolding, props or formwork are required over the supports, thus reducing construction site activities, improving safety margins and eliminating in-situ casting work (except sealing off the construction joints and some minor details).
• Ease of handling/transportation and installation - DURA^® PSF is about the same total weight when compare to steel structures.
• Members used in DURA^® PSF are guaranteed volumetrically stable as steam curing was employed to reduce creep and accelerate all long term shrinkage of the UHPdC.
• DURA^® PFS can be produced to desire dimension with incremental width of 10 ft. Spans outside the indicated range can be considered on request.
• Due to its high durability, high ductility and high fatigue strength, it provides excellent resistance against impact and abrasion loads.
• Dura^® PFS is supporting the green visionary as it is a more environmental freely material compare to steel structure.
