Expanded Sheet

What is Expanded Sheet?

Expanded sheet has many different uses. It is also advantageous in terms of physical and cost. The expanded sheet, which is supplied as one-piece and with a very light structure, is also known for its use in most areas. The product, which is produced as stretched or expanded sheet, offers light, air and liquid permeability.

Expanded sheet metal, whose dimensions can be determined specifically for spaces, is prepared and manufactured according to standard dimensions that are compatible with standard pan suspensions. In addition to the standard production feature, in addition to this, procedures can be made according to the customer’s request in product production.

Extended sheet metal programs, which will bring a contemporary and quite modern atmosphere to the project to be realized, also offer many advantages together. Considering the advantages, ease of use and usage effects, expanded metal prices appear as a very economical choice.

Stainless steel and aluminum materials are used in the manufacture of the product, which is presented as a kind of metal sheet.

Descriptions

1) The quality specified in this table is produced in İsdemir facilities within the framework of agreements made with customers.

2) In this quality, it is produced in such a way that there is no roll breakage.

3) Mechanical testing is not done according to production practices.

4) In the chemical composition of the steel, min. For grades with 0.020% Al, the upper limit value of N is not applied.

5) These grades are produced as fully stagnant and have a minimum Al/N ratio of 2:1.

6) Carbon equivalent is calculated according to the formula CEV (IIW) % = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15.

7) For S275 and S355 grades, max. carbon equivalent (CEV) is increased by 0.02% for %Si ≤ 0.04 and 0.01% for %Si ≤ 0.25.

8) It is suitable for galvanized coating as “Category A”. Si ≤ 0.030% and Si+2.5P ≤ 0.090% limits apply in Category A class

9) It is suitable for galvanized coating as “Category B”. Si 0.14≤ Si ≤0.25% limit is applied in Category B class.

10) In line with the production practices, the suitability for galvanized coating can be considered subject to negotiation at the order stage. Classes of suitability for galvanized coating Category A

Si ≤ 0.030% and Si+2.5P ≤ 0.090% limit in Class B, Si 0.14≤ Si ≤0.25% limit in Category B class, Si 0.25< Si ≤0.35% limit in Category D class.

11) Max. It is produced up to 8 mm thickness.

Usage areas

Expanded sheet metal products have a very wide usage area. Expanded sheets, which can be found in many different areas ranging from small products to large construction programs, are sometimes a material that provides superiority with their use, sometimes they can be used in decoration and sometimes in production as an option other than this. The fact that the product usage areas are wide can also be determined by the superior features in the product offerings. In addition to this, while having quality with reasonable price, it also supports production with an economical choice.

What are the features

– The maintenance costs of expanded sheets are low.

– It has a clear field of vision.

– There is no possibility of climbing as there is not enough space on the sheet for hands and feet to enter.

– Extended Sheets have a long-lasting use.

– Since the welding process is not performed, there is no possibility of rupture and breakage.

– It is resistant to impacts.

– Since its square meter weight is light, it is economical in terms of cost and does not put too much weight on the structure to be used.

– The sheets produced are easy to stack, assemble and transport.
