GNEE STEEL metal coated steels are low carbon steels designed for forming parts produced by deep drawing, bending or roll forming. They have very high ductility and formability and are suitable for manufacturing a wide range of cold formed parts. These steel grades comply with EN10346:2015.
GNEE STEEL product range features metal coated formable steels with a zinc (Z), galvalume (ZA) or galvannealed (ZF) coating. The electrochemical corrosion protection of these galvanized products allows for a long service life of the end product when used under corrosive conditions.

DX53D, DX54D, DX56D and DX57D are non-ageing steels, i.e. their properties will remain unaltered at least for six months
1) If no pronounced yield point is present, the 0.2 % yield point value Rp0,2 is used. If the product has a pronounced yield point, the values apply to the lower yield point ReL.
2) DX52D: this upper limit applies only to Surface quality B. For Surface quality A, the upper limit is 360 MPa.
3) Decreased minimum elongation A80 value for thickness 0.50mm < t ≤ 0.70mm (minus 2 units) and t ≤ 0.50mm (minus 4 units) apply. In addition, in case of ZF coating on DX54D or DX56D the minimum elongation A value is reduced (minus 2 units).
4) DX54D: decreased minimum r90-values for product thickness 1.5mm < t < 2 mm (minus 0.2 units) and t ≥ 2 mm (minus 0.4 units) apply. In addition, in case of ZF coating the minimum r90-value isreduced (minus 0.2 units).
5) DX56D and DX57D decreased minimum r90-values for product thickness 1.5mm < t < 2 mm (minus 0.2 units) and t ≥ 2 mm (minus 0.4 units) apply.
In addition, in case of ZF coating both minimum r90-value (minus 0.2 units) and minimum n90-value (minus 0.01 units) are lower and further the following reductions apply:
- decreased minimum r90-values for product thickness 0.50mm < t ≤ 0.70mm (minus 0.2 units) and t ≤ 0.50mm (minus 0.4 units).
- decreased minimum n90-values for product thickness 0.50mm < t ≤ 0.70mm (minus 0.01 units) and t ≤ 0.50mm (minus 0.03 units)
Material Testing
Testing direction transverse to the rolling direction.
Each metal coated mother coil is regarded as one test unit. Mechanical properties (EN-ISO 6892-1:2009) and coating mass (EN 10346) are determined per test unit.
An inspection document of the required type according to EN 10204 is provided when agreed in the order.
Coatings
The metal coated products are offered with Zinc (Z), Galfan zinc-aluminium (ZA), or Galvannealed zinc-iron alloy (ZF) coating. The cathodic corrosion protection of these metal coatings is in direct proportion to its thickness, i.e. a thick coating will provide better corrosion protection for the underlying steel than a thin coating. However, thin coatings are recommended for applications with high formability requirements.
Surface Quality
Normal surface (A)
Imperfections such as pimples, marks, scratches, pits, variations in surface appearance, dark spots, stripe marks and light passivation stains are permissible. Stretch levelling breaks or run-off marks may appear. Coil breaks and stretcher strains may appear as well. Surface quality A has a shiny appearance.
Improved surface (B)
Surface quality B is obtained by skin passing. With this surface quality, small imperfections such as stretch levelling breaks, skin pass marks, slight scratches, surface structure, run-off marks and light passivation stains are permissible. Surface quality B has a matte appearance.
Surface Treatments
In order to prevent formation of white rust during transportation or storage, the following surface treatments are available:
Chemical passivation (C)
Oiling (O)
Chemical passivation and oiling (CO)
Unprotected (U)
