FAQ:
What is the Australian standard as 1163?
Australian Standard AS1163 is a standard published by the Australian Standards Institute, covering requirements for steel structure design and construction. The standard AS1163 includes provisions regarding structural steel materials, design requirements, manufacturing, installation, and acceptance. The derived AS1163 standard has corresponding sections covering specific content in different aspects. If you need specific information, you can refer to the specific AS1163 standard document(as nzs 1163 pdf) or consult us.
What is cold-formed structural steel hollow sections?
Cold-formed structural steel hollow sections are tubular steel components made by shaping steel sheets or strips at room temperature. They are used in construction for things like building frames and support columns because they are strong, lightweight, and can be made in different shapes and sizes. They are cost-effective to produce and offer design flexibility for various applications in construction projects.
What is C350LO steel?
C350LO steel is a structural steel grade designed for construction purposes. It is commonly used in building projects due to its strength and durability.
What is the difference between C250 and C350 steel?
The main difference between C250 and C350 steel is their strength. C350 steel is stronger than C250 steel.
What are the properties of grade C350 steel?
C350 grade steel is a medium strength structural steel with good ductility and weldability. It is commonly used in building and engineering applications that require strength and durability.
What steel grade is As1163 C350 equivalent to?
