Ladders, Work Platforms and Scaffolding

Ladders and platforms manufacturing process


ESLA has a design manual regarding the standardization of its products

As manufacturers, we assume full responsibility for ensuring that our products fulfill the following work health and safety regulations where relevant:

  • Royal Decree 486/97 WORK PLACES
  • Royal Decree 1215/97 WORK TEAMS

In addition, all legal points referring to ladder components or ladders as a whole are fully respected during the quality assurance and product design processes. This serves to ensure that all specific requirements as detailed in the specifications are complied with, based on the following European technical norms:

  • UNE-EN 131:1993 LADDERS
  • UNE-EN ISO 14183:2003 STEP LADDERS

Aluminum and its properties


Aluminum doesn’t burn nor emit any type of toxic substance. Its melting point is at 660º C.


Aluminum is an especially ductile material. It can be manufactured in an infinite variety of adaptable shapes to meet the specific requirements for its use.


Aluminum has been recycled since the outset and is 100% recyclable. It can be recycled indefinitely without losing any of its physical properties or quality, enabling the manufacture of 100% recycled aluminum products.

  • Energy savings during its recycling and production processes.
  • Its harmlessness.


Barra de aluminio

The natural oxidation of aluminum creates a protective and permanent layer which protects it against atmospheric and chemical agents, making it highly resistant to oxidation. This layer regenerates sridgeaneously when accidentally or intentionally eliminated.

The different types of surface treatments available also improve on this condition. Some type of treatment is necessary depending on the application of the aluminum. Included among the most common treatments for aluminum are anodizing and lacquer.

Aluminum has an extremely long useful life. Similarly, aluminum reflects ultraviolet radiation and, as such, does not suffer from the chemical or structural changes caused by ultraviolet rays on other commercially used materials.

Aluminum is especially useful for applications requiring protection, conservation and durability.

Structural resistance

Aluminum is a very light metal, weighing 2.7 g/cm3, a third the weight of steel.

The aluminum used for commercial purposes is an alloy, thus offering a wide variety of characteristics suited for the most diverse applications.

Given that rigidity does not only depend on elastic qualities but also the shape, aluminum can offer the same rigidity as steel at a third of the weight. At little additional cost during the mechanization process, additional elements can be added to increase its torsion rigidity.

Non toxicity

Aluminum is an innocuous, hygienic and scent-free material.

Its excellent barrier qualities completely impede the filtration of water, oxygen, smells, other gases and microorganisms. By the same token, its surface is easy to clean and keeps bacteria from collecting and growing. All these properties encourage its use in diverse industries such as health, food and construction.

Fabricación de escaleras y plataformas de acceso para diferentes sectoresHow do we carry out a made-to-order projects?

ESLA has the technical capacity to carry out any project, from the client’s original sketch to the final delivery.

The client presents an initial sketch for a new project depending on his needs.

Realización de croquis y planos de escaleras y plataformas

The corresponding design and technical study are carried out.

Prueba de materiales para la construcción de escaleras y plataformas

The quality assurance department is in charge of the necessary tests according to current legislation.

Proyectos certificados según necesidades del cliente

The product received by the client is certified to meet the requirements indicated.

Means of access selection

The first thing to be determined before deciding on the type of access is the type of work to be carried out and the frequency of use. It is common sense that this should be the first thing to examine given that each type of situation requires distinct properties.

We also have to bear in mind that the minimum safety measures to include will vary depending on the type of access in each case. Generally, the difference can be established between access to a machine or to another more general work area or between access to floors in an assembled building or scaffolding.


Means of access consisting of a continuous inclined plane with a slope angle ranging from 0º to 20º.

Means of access with a slope angle over 20º and up to 45º on the horizontal elements (steps). It is aimed for frequent use and/or people carrying tools.

Step ladder:
Means of access with a slope angle ranging from 45º up to 75º on the horizontal elements (steps). Its frequency of use is less than that for a ladder and for people not carrying tools except light objects such as screwdrivers, brushes, etc. For angles equal to or greater than 60º, we recommend descending the ladder face-forward.

Vertical ladder:
Means of access ranging from 75º to 90º on the horizontal elements (steps). It is aimed for occasional use, and both hands should be used to hold on.
