Over 50 years of continuous innovation

Since 1968, ETESA has been manufacturing and distributing high quality wear parts and attachments for the major earthmoving equipment brands for the Mining, Quarrying, Public Works and Construction industries.


Through our experience, innovation and expertise gained in steelmaking over 50 years, in 2003 we expanded our operations and began producing wear parts for the agricultural sector.

Our values

Over 50 years of experience. Largest variety in Wear Parts solutions

Highest standard throughout the production process

Focus on building long-term relationships

Open information sharing from day one

Efficient and effective processes and products

The [ETESA] solution

Did you know…?

Consumption of spare and Wear Parts contributes significantly to the maintenance costs of earthmoving machinery.

And these high maintenance costs dramatically affect productivity gains and profitability:

Therefore, it is critical to choose the right GET based on:

Quality of the alloy steel
Site application

Production shortcuts

Poor manufacturing leads to substandard quality parts that are fragile  or show premature wear. This results in:

Increase in equipment downtime
Increase in overall operating costs
Increase in  risk insurance premiums

Benefits of trusting ETESA

Increase in the overall performance of the equipment

Reduction of downtimes

Extension of the service life of equipment and buckets

Lower maintenance and operating costs

Less fuel consumption

Reduced risk onsite

ETE steels

The experience obtained over 50 years in steelmaking has resulted in compositions with excellent mechanical properties to match the type of terrain, application and working conditions.

ETE steels are high strength quality alloy steels with an optimal ratio between HARDNESS and TOUGHNESS. In addition, ETE steels are subjected to an exclusive heat treatment process that reduces impact breakages and increases resistance to wear under the most demanding working conditions.


Traditionally, overall quality of the wear alloy steel has been measured by hardness with the view that the greater the hardness the higher the resistance to wear and therefore the longer the service life of the parts.

ETESA has developed their own heat treatment process applied to all their ETE steels. This process results in a tough steel with an even and consistent distribution of the hardness from the surface to the core of the part.

However, toughness is just as important as hardness. Toughness shows the steel’s ability to deform and absorb impact before breaking.

ETE steels are extraordinarily resistant to due to the grain in the steel that is homogeneous and free from impurities. This is obtained through ETESA´s heat treatment that guarantees optimal energy absorption upon impact. In addition, strict quality controls are performed to make sure that all parts are free from pores and fissures.

To obtain hard and tough steels, it is necessary to apply an additional heat treatment afterwards to allow the steels to reach their optimal state. The longer and more exhaustive this heat treatment process is, the greater quality and higher performing the steel becomes.

At ETESA all our wear parts are subjected to a thorough heat treatment process ETE3TT developed in-house at our own foundry in Spain. This treatment allows our steels to obtain great hardness while maintaining an optimum balance with impact breakage.

R&D and Quality control

At ETESA there are no shortcuts taken when it comes to quality for any of our wear solutions. Our highly qualified technical department oversees all our production processes and quality assurance.


Our team begins by designing the parts to be manufactured based on the individual demands and requests of our clients. We use state-of-the-art 3D scanning techniques, prototyping and the latest moulding software.
This allows us to obtain a graphic simulation to assess the performance of each part under different working conditions prior to production.

Moulding & tooling

Next, moulds are made to produce the steel parts by either casting, forging or hot stamping depending on the requirements of each part and with a focus on the efficiency on the equipment it will be fitted to.


The quality control department ensures the highest standards from the production stage to delivery to our customers. Moulds are kept in perfect working condition. By performing thorough tests, both at the factory and later at our warehouses, we make sure all parts from the foundry are in optimal condition.

Every part supplied by ETESA comes with lifetime warranty against breakage – this is our commitment to you
