History and Presentation Gavex is a Steel Service Center with multiple Cutting Lines for processing steel coils into strips and sheets, having a large stock of steel products. Gavex has its headquarters in Ovar, located between Oporto and Aveiro with a distance of 35 km from each, over an area of 22.500 m2, with covered installations about 8000 m2 This company was established in 1967, having then the social assignment Gavex - Exportadora de Gavinho , Lda. The first years of its activity had been dedicated to the commerce of ropery, tapestry and similars. In the decade of 70, as result of Overseas war ending, Gavex changes its activity to Steel Sector. In 1992/1993, Gavex installs its first Cutting Lines: Slitting, cut-to-length and levelling, with feeding and packaging systems. In 1997/1998, Gavex installs a new cut-to-length Line, increasing its capacity to process materials with bigger thickness. In 2005, Gavex strengthening its expansion policy, increases again its operational capacity, installing a new Slitting line, to satisfy each time better the customers

Hot rolled Steel – bending and deep drawing

Steels for bending and deep drawing applications are

intended for cold forming. They are used when deformation

and ductility properties are more important than strength

properties. They find application in the automotive industry

and related sectors. These steel grades are also used for a

wide range of bending and deep drawing applications in

machine manufacturing, building, metal processing, etc.

These grades can be used for normal (DD11) up to very

deep drawing applications (DD14). The more high it is the

number that represents in the larger designation will be

his/her capacity for deep drawing.

They have application in the industry automobile and

related sectors; being also used in the machinery

production, construction, metallic processing’s, etc.

The products below can be supplied:

1. Unpickled:

Without superficial protection;

Without surface finishing after pickling.

2. Pickled and oiled:

Have a superficial finishing, after pickling;

With superficial protection (oil).

Hot rolled steel - Structural

Structural steels are mainly used in building industry and

mechanical constructions. Applications include building

components, containers, storage tanks and roll formed

profiles. These steels are not specifically micro-alloyed.

They show good weldability with conventional welding

processes and in most cases do not require pre or post-

heat-treatment. In addition to their good mechanical

characteristics, they also have very acceptable toughness

values.

Electrogalvanized products are coated with pure zinc

or a zinc-nickel layer. Both coatings can be applied

one-sided or two-sided. Electrogalvanized products

combine good corrosion resistance, with outstanding

surface finish conditions to printability. The products

furthermore present excellent drawing and welding

characteristics, which makes them particularly well

Coated steel - galvanized

Hot dip galvanized steel consists of a high quality

steel substrate with a thin metallic zinc or zinc-iron

coating which is applied by means of a continuous

hot dip galvanizing process. Hot dip galvanized

products offer extraordinary protection against

corrosion, not only because of the galvanic

protection of the zinc, but also by the physical

barrier of the coating itself. These products have a

large number of applications and can be used both

indoors and outdoors. Some of the most common

applications are: Automotive Industry, Building,

Domestic Appliances, etc.

Organic coated

With organic coated products, a liquid paint system is

applied to a metal substrate by means of a continuous paint

process. Organic coated (prepainted) flat steel products are

replacing post-painting of the finished product. The process

is also environmentally friendly, economical and guarantees

consistent product quality. This type of coating can be used

in different types of material, with hot dip galvanized steel

as the most frequently used grade. Various liquid paints in a

range of colours can be used to coat the substrate.

A multi-stage cleaning process and chemical pre-treatment ensure optimum bonding of the coating

and improved corrosion resistance of the steel. Organic coated products are used primarily in the

building industry (roof, wall and ceiling claddings), electric appliances (fridges, washing machines),

the transport sector, radiators, office furniture and packaging.

Elongation (A80) - When a material is tested for tensile strength it elongates a certain amount before fracture takes place. The two pieces are placed together and the amount of extension is measured against marks made before starting the test and is expressed as a percentage of the original gauge length. Elastic deformation (E) - Deformation that is not permanent, in other words, that it is totally recovered when it is stopped applying the load or tension that it provokes the deformation. Plastic deformation (E) - plastic deformation is not recoverable, i.e. the change is permanent. Hardness - it measures the resistance that a material offers when force is applied by other material. Tension (σ) - Is a force applied by stretched string on the objects which stretch it, being measured as the applied force by unit of area.

Resilience (KV) - is defined as the capacity of a material to absorb energy when it is deformed elastically and then, upon unloading to have this energy recovered. In other words, it is the maximum energy per volume that can be elastically stored. Traction (F) – is a strength applied to a body, according to one axis, in a way to produce an extension in the direction of the axis.
