Steel vs. Concrete

Time：2021-10-02 Hits：370

As commodity prices fluctuate, so does architectural design. In times of lower steel prices, more steel and less concrete are used, and vice versa. Each group of suppliers and users usually maintain national industry associations that advocate the use of their materials over the other. However, both materials are typically used together. Unreinforced steel concrete (usually round ribbed bars called rebar) crumbles under tensile loads. Steel alone, without solid concrete floors, is also not a preferred construction method.

While rebar is always steel, it is not considered structural steel and is described separately in the rebar and reinforced concrete items. While both steel structures and reinforced concrete (RCC) concrete structures have their pros and cons, steel structures have a better strength-to-weight ratio than RCC ones and can be easily disassembled (steel structures, which have bolted connections can also be reused to some extent). After disassembly).

- Sheet roofs

Metal roofing is a very versatile building material, which is durable. It can be used in residential, commercial, industrial or agricultural buildings. It is not only used in roofing applications, but can also be used as a wall cladding. There are many different profiles and styles available to suit most construction situations.

Metal roofs under new construction

Metal roofs are ordered by each piece, either in sheets, moldings or ridge material. When they are correctly estimated, there is very little waste material in a new project. Sheets can be ordered and cut into exact lengths, allowing for less cutting on the job.

Metal roofs under renovation

Metal roofs are easily applied over an existing roof. Especially in situations where reducing labor costs is essential, the added value of not having to remove existing roofing material can be of great help.
