What is steel deck KSI?

What is steel deck KSI?

Steel deck is profiled cold-formed sheet steel used as roof deck, non-composite floor deck or composite floor deck and is typically made of coated cold-rolled steel with yield strengths ranging from 33 ksi to 80 ksi.

What is the strongest type of steel deck?

W3-36 is the strongest metal floor deck. It’s available as light as 22 gauge and as heavy as 16 gauge.

What is KSI rating?

1,000 kilos per square inch
Steel strength (or quality) is measured in KSI or Kilopounds per Square Inch with one KSI being equal to 1,000 kilos per square inch (you can convert to PSI or Pounds per Square Inch using a KSI calculator). The higher the KSI the stronger the steel.

How far can steel deck span?

Capable of open spans of up to 60 feet and beyond, composite steel joist and steel deck long-span composite floor systems provide design flexibility while introducing a range of cost and performance enhancements.

What is 50 ksi steel?

This steel has a yield strength of about 40,000 – 50,000 PSI (pounds per square inch), or 40-50 KSI (kilopounds per square inch). As you can see, commercial quality cold rolled steel offers some bend resistance — that’s why it’s popular for roll formed shapes and fabricated assemblies.

What is steel deck made from?

Steel deck is a cold formed corrugated steel sheet supported by steel joists or beams. It is used to support concrete or insulating membrane of a roof.

How far can metal roof deck span?

N Roof Deck: Type N-24 The deeper the panel is, the stronger the panel is and the further it can span. Type N-24 can span distances ranging from 6 feet up to 16 feet. It is used in different applications such as roofs, canopies, and awnings.

Can steel deck use for roofing?

Steel roof deck allows easier installation of roofing materials, waterproofing, insulation, and lightweight concrete.

How strong is 50 ksi?

This commercial-grade steel is very readily available — most steel service centers have it on the shelf, at a low cost. This steel has a yield strength of about 40,000 – 50,000 PSI (pounds per square inch), or 40-50 KSI (kilopounds per square inch).

How much does it cost to build a 20×20 deck?

The average homeowner spends $2,200 to build a 10×10 foot deck, $6,160 to build a 14×20 deck, and $8,800 to build a 20×20 deck. The cost to build a deck with pressure-treated wood, hardwood, or composite is about $25 per square foot, for both materials and installation.

What is the standard size of steel deck?

Deck lengths can be varied to suit job conditions but, because of shipping considerations, are usually less than 40′. Standard deck width varies with the product used but full sheets are usually 12”, 18”, 24”, 30” or 36”.

How strong is an 8.8 bolt?

Bolt Grade Markings and Strength Chart

What is the advantage of steel deck?

Slabs made with steel decking have high structural strength compared to traditional concrete slabs. This creates a high strength-to-weight ratio which allows for a massive weight reduction.

What is the minimum bearing for metal deck?

1-1/2″
A minimum of 1-1/2″ of end bearing should be provided for metal roof decking or metal floor decking. If there is less than 1-1/2″ of bearing, additional fastening should be provided and the deck end load capacity should be checked.

What is the advantage of using steel deck?

Using steel and roof deck/Resindek® can lower a project’s overall cost and use fewer materials, and many times other materials are more durable than concrete and more flexible with their application. There are also construction and installation concerns with a concrete deck system.

What does KSI mean engineering?

kilopound-force per square inch
A related unit is ksi, which stands for kilopound-force per square inch.

What is KSI in hardness?

Yield strength , or working load limit, is the amount of stress a material can withstand without permanent deformation. Tensile strength is the maximum amount of axial stress that a material can take before breaking. All strength measurements are in ksi (kilo-pound per square inch).

How much does a 500 square foot deck cost?
