Steel encasement systems
Box encasement turns a steel member into a clean, square, fire-protected element – the details are as important as the board.

World Steel が鉄骨建築と一括で、または単体で供給 – 一つの注文、一つの出荷、一つのパートナー。
概要
Steel encasement systemsについて
A box encasement is built from fire boards fixed to noggins, steel angles or directly to each other around the section; the tested system defines board thickness, fixing spacing and joint treatment.
Boxed protection is sized using the boxed section factor (heated perimeter of the box) under EN 13381-4, BS 476-21 or ASTM E119 data.
Penetrations and connections to walls and slabs need tested details or firestop products.
主なメリット
- Clean, square architectural finish
- Dry, low-mess installation
- Long ratings achievable
- Inspectable thickness

FAQ
よくある質問
Why does the section factor change with boards?
Board encasement heats the steel through the box perimeter, so the boxed section factor is used – usually lower than the profile value, needing less protection.
Is this product certified?
Certification belongs to a specific manufacturer’s product or tested system. We supply the test report, classification or listing accepted in your market for the product selected – it is confirmed per project, never assumed.
