Integral management

Integral management of poles and columns for street lighting

HGH’s priority is the quality of their poles, columns and metal supports for street lighting that we manufacture and; to achieve this quality, there is no better way than to comply with the applicable regulations and standards, in our case the European ones. To ensure quality, we have our own Quality Department with resources and engineers geared toward product quality, process control and continuous improvement.
To ensure that all our materials meet the required quality standards, at HGH we monitor all phases of the production process.


The sheet metal used by HGH for the construction of the poles and columns is of the maximum thickness and quality specified in the European Standard.

In addition, suppliers are evaluated from the beginning of the process and continuously monitored to ensure their suitability and adequacy. 

The evaluation and subsequent selection of our suppliers is carried out through the control of two fundamental lines:

1) Quality system:

  • Implementation and compliance.
  • Third party certifications.
  • Delivery history (quality, deadlines, prices)

2) Product safety:

  • Safety, legislative, restricted use, toxic or dangerous component and environmental requirements.
  • Specification fulfilment.

The stability in the production processes, which employ state-of-the-art production methods, is a product quality guarantee. In our galvanising process, our carbon steel poles and columns are subject to an anti-corrosion surface treatment by deposition of electrolytic 99.995% purity Zinc. Products are submerged in a hot galvanic bath in accordance with ISO 1461 standard and comply with the requirements established in the ISO 752 standard. Our products are delivered with a quality certificate and are subject to thickness control in the galvanic treatment.

During the process, all manufactured material is subject to strict control, while the final product is checked by our Quality Managers (Product Auditor) before it leaves the factory.

Material delivery:
The delivery of the poles and/or columns is managed in agreement with the client, complying with the logistical requirements specified by the client and following current transport legislation.

Quality is our hallmark and helps us stand out in the market. The certificates that accompany our products: CE, N, IQ, AENOR, ISO.

In addition to manufacturing in accordance with European quality standards, our standard products are certified with the CE marking and with AENOR’s N if they are manufactured for Spain.

Our management system is also certified, endorsed by ISO 9001 by AENOR and IQNET.

Commitment to the Environment


HGH sees value creation not only from the perspective of financial criteria (profitability) but also by incorporating environmental, social and good corporate governance criteria into its business strategy. This way, corporate social responsibility policies and ethical behaviour are integrated in order to improve transparency and facilitate decision-making.

From the environmental point of view, this policy is based on a series of targeted actions, among which we highlight the following:

Identification, segregation and treatment of waste by authorised waste managers in the Support Factory.

Integrated Environmental Authorisation of the Galvanising Plant, which includes all environmental and related aspects considered by the competent environmental authorities, both at state and regional level. Compliance with the emission limit values (ELVs) set in the AAI and based on the Best Available Techniques (BAT), which are reflected in the Conclusion Reports.

Our products comply with current environmental regulations throughout the production process.
