AHMSA´s cold rolled products comply with the

highest international quality standards. Cold

rolled steel, tinplate and tin-free steel

production processes are certified under

ISO 9002 standard. In order to satisfy the

requirements of the automotive industry,

AHMSA´s Cold-rolling mill Nº 2 received the

QS 9000 standard certification and VDA 6.1

certification for the German automotive market.

AHMSA´s Cold-rolled facilities are also certified

under the ISO 14001 standard, which allows a

complete protection to the environment during

the product manufacturing process.

With a wide variety of grades and specifications

in its cold rolled products, AHMSA fulfills the

different steel applications required by the

automotive, home appliance, motor lamination

industries, among others. AHMSA is the only

producer of tin-free steel and the main

producer of tinplate in Mexico.

The grades in this catalogue represent our main

product line. Some of them require a minimum

volume for their production and/or are subject

to certain restrictions.

COLD ROLLED STEEL



2

Also known as chromed steel, tin-free

steel (TFS) is obtained by coating the

metal base (low-carbon steel) with an

ultra-thin layer of metallic chrome and

then with a chromium oxide layer.

The product complies with ASTM A-657

Specification and is manufactured with

low current density (TFS-III) and is

supplied only in coils of up to 12 metric

tons.

Tinplate is a light gauge, low carbon, cold

reduced steel on which tin is applied on

both sides by electrolytic tinning. Since the

tin firmly adheres to the base metal, the

product may be press molded, stamped,

drawn or bent and shaped into complex

forms without the tin coating peeling off.

This product fully complies with ASTM

A-624 Specifications and is supplied in

coils of up to 12 tonnes or cut in sheets

meeting the following guidelines:

Also known as chromed steel, tin-free

steel (TFS) is obtained by coating the

metal base (low-carbon steel) with an

ultra-thin layer of metallic chrome and

then with a chromium oxide layer.

The product complies with ASTM A-657

Specification and is manufactured with

low current density (TFS-III) and is

supplied only in coils of up to 12 metric

tons.

rolled steel, tinplate and tin-free steel

production processes are certified under

ISO 9002 standard. In order to satisfy the

requirements of the automotive industry,

AHMSA´s Cold-rolling mill Nº 2 received the

QS 9000 standard certification and VDA 6.1

certification for the German automotive market.

AHMSA´s Cold-rolled facilities are also certified

under the ISO 14001 standard, which allows a

complete protection to the environment during

the product manufacturing process.

With a wide variety of grades and specifications

in its cold rolled products, AHMSA fulfills the

different steel applications required by the

automotive, home appliance, motor lamination

industries, among others. AHMSA is the only

producer of tin-free steel and the main

producer of tinplate in Mexico.

The grades in this catalogue represent our main

product line. Some of them require a minimum

volume for their production and/or are subject

to certain restrictions.
