Group Activities & Contribution to the Industry

We Also Build and Contribute Beyond Telecom

Our other lines of business and solutions we developed ourselves for problems seen in the field.

Business Line

MEKAP — Life & Workplace Safety

We are the regional distributor of MEKAP workplace safety products in Eastern and Southeastern Anatolia.

Business Line

OHS Equipment Store

Through our store selling workplace safety equipment, led by hard hats, safety shoes, safety harnesses and personal protective equipment, we support our field teams and the industry with quality products.

Industry Contribution

Anti-Theft Battery Cabinet

To stop battery thefts at sites, we manufactured our own project-designed battery cabinet. Its multi-point locking makes removal slow, which deters thieves; it has been used at high-risk sites in Southeastern Anatolia with positive results.

Industry Contribution

A Letter from OGEM to the Family

An industry first: we sent letters to our employees' families, asking them to share our commitment to workplace safety. We observed a rise in motivation and sense of belonging.

From Our Depots and Offices

With depots and offices close to the field, we route materials and crews quickly.
