Ceiling and Wall Penetrations

Reliable V2A/V4A stainless steel pipe penetrations ensure watertight and hygienic routing of pipes and cables in tunnel construction, food industry and process installations. Corrosion-resistant, customizable to client needs in terms of diameter and length, with finishing option for greater durability. Ideal for standard and custom projects.

Pipe penetrations – ideal sealing solution for construction

Stainless steel pipe penetrations from B&K GROUP provide a reliable, versatile solution wherever safe, watertight routing of pipes or cables through building levels is required. Whether for tunnel construction, food industry, process installations or technical infrastructure – the right pipe penetration enables efficient, hygienic installation of service and supply lines from point A to point B.

Our pipe penetrations are made of high-quality V2A or V4A stainless steel, ensuring durability, corrosion resistance and easy cleaning – even in extreme conditions. Each product is individually tailored to client requirements, offering a choice of inner diameter and pipe length according to project specifications.

Additionally, penetration surfaces can be finished by pickling or glass-bead blasting, improving aesthetics and increasing resistance to chemical and mechanical factors.

For non-standard projects we also supply custom-made models according to client technical documentation, guaranteeing maximum tightness, safety and precise fit.

Frequently asked questions

How do stainless steel ceiling and wall penetrations differ from standard sleeves?

They are watertight V2A (1.4301/AISI 304) or V4A (1.4404/AISI 316L) stainless steel pipe penetrations that provide hygienic, durable routing of pipes and cables through slabs and walls. Unlike mild steel, they resist corrosion and are easy to clean.

When should I choose V4A instead of V2A?

V4A (1.4404/AISI 316L) contains molybdenum, making it resistant to chlorine, acids and salt. It is ideal for food industry, process installations and aggressive chemical environments. V2A (1.4301/AISI 304) suffices in less demanding conditions.

Do you manufacture ceiling and wall penetrations to custom sizes?

Yes. Every penetration is made to order: inner diameter and pipe length are selected according to documentation and project requirements. We supply both standard models and fully custom stainless steel products manufactured in-house.

What surface finishes are available for pipe penetrations?

Joints are TIG/MIG welded for watertight, durable and hygienic connections. Smooth stainless steel surfaces facilitate cleaning and improve corrosion resistance, meeting elevated sanitary requirements.

What certificates confirm the quality of stainless steel penetrations?

The stainless steel holds PZH approval for food contact and can be supplied with 3.1 material certificate according to EN 10204. As an EHEDG member complying with HACCP, our products meet food-industry hygiene standards.

Where are stainless steel ceiling and wall penetrations used?

They are used wherever pipes or cables must be routed safely and watertightly through slabs and walls: food industry, process installations, technical infrastructure and tunnel construction. See our full range of stainless steel products.
