Reinforced Concrete Modular Shelter Honor for up to 40 People 4Mx2

BUNKER-OK is a Ukrainian engineering brand providing modern shelters and civil defense solutions for the private sector, business, and civil and strategic infrastructure.

We design and manufacture protective structures, systematically improving them based on practical operational experience, analysis of shelling consequences, and the actual behavior of structures during combat strikes.

Drawing on the experience of over 400 installed shelters, the BUNKER-OK team has reached an unequivocal conclusion: not every structure that looks like a shelter is capable of providing the proper level of protection.

We have studied actual destruction and structural weaknesses of low-quality installations, and we responsibly state: effective protection is determined not by the volume of concrete, but by structural integrity and a well-engineered reinforcing cage that stops shrapnel, localizes impact damage, and saves lives.

That is why the BUNKER-OK team is the first in Ukraine to establish CPS (Civil Protection Standard) — a next-generation quality standard.

CPS was created based on physical loads, engineering expertise, and field testing against modern combat threats, including:

• 120 mm OF-843 mortar shell
• 125 mm OF A-IX-2 tank shell
• HE-Frag warhead of the Shahed-136 strike UAV (47.8 kg)

In today's reality, the legally established testing standard of 2 kg of explosives (TNT) is increasingly becoming just a basic regulatory threshold. It rarely corresponds to the scale of modern threats, cannot be considered a comprehensive indicator of protection, and is not a convincing basis for evaluating a shelter's reliability.

The CPS quality standard by BUNKER-OK significantly exceeds current state requirements and sets a new safety benchmark for the market.

We are convinced: the CPS quality standard must become the fundamental basis of choice for every buyer and a new benchmark of quality for every shelter manufacturer.

BUNKER-OK is not just a manufacturer.
We are a company shaping a new culture of protection in Ukraine and worldwide.
