Langmatz QualityBox
Innovation and quality for over 30 years
Special features of the QualityBox
-
3D ribFrame technology: patented 3D ribFrame technology lends the QualityBox exceptional stability, load bearing capacity, and durability. Our internal engineering ensures that all components are perfectly coordinated to each other, improving overall structural engineering performance.
-
Polycarbonate (PC) is a versatile, durable, high-performance plastic that offers excellent toughness, breaking strength, and impact resistance. Its temperature resistance also sets it apart. PC is an amorphous thermoplastic devoid of plasticisers.
-
Practical predetermined breaking points, which can be removed by tapping them through with a hammer without this affecting the structural strength of the manhole, simplify installation.
Development and production: Made in Germany
Langmatz develops and produces in Germany. Our decades of experience in injection moulding guarantee the highest level of quality and durability. Our modern machinery and stringent quality controls – including incoming goods inspections, batch monitoring and 3-point bending tests – guarantee consistently high product quality. Langmatz also has a unique static load hydraulic press that is able to simulate all pressure loads relevant for road construction.
Cover design and in-house manufacturing
Cover designs meet stringent DIN standard requirements. The high rate of in-house manufacturing, which ranges from processing the steel sheet metal to the finished cover, ensures durable and standard-compliant products. These are monitored externally in accordance with DIN EN 124.
Sustainability and recycling
Langmatz adheres to a sustainable approach to production by shredding high-quality plastic waste, and returning it to the production cycle by compounding.
Comparison between DIBt and ETA
DIBt (German Institute for Building Technology)
The German Institute for Building Technology assesses and approves construction products and types of construction for Germany.
- Responsibility:
National approval body in Germany for construction products not covered by harmonised standards. -
Advantages:
- National expertise and specific adaptations for the German market.
- High safety and quality standards. -
Application:
Ideal for products used exclusively on the German market.
ETA (European Technical Assessment)
A European Technical Assessment (ETA) is prepared in the European Assessment Document (EAD) on the basis of technical specifications.
-
Responsibility:
EU-wide recognised assessment of construction products based on European Assessment Documents (EADs) not covered by harmonised standards.
-
Advantages:
- Facilitates EU-wide distribution without the need for additional national approvals.
- Comparability by means of a mandatory Declaration of Performance.
- Transparent and publicly accessible test criteria. -
Application:
Ideal for products distributed in multiple EU countries or for which there is no harmonised standard. The ETA may include features which may not have been taken into account in existing harmonised standards.
Common features of the DIBt and ETA
- Both institutions (DIBt & ETA) evaluate the performance of construction products and guarantee high quality and safety standards.
-
The tests are carried out by independent accredited bodies
Differences in requirements
- EOTA: Evaluates specific product requirements independently of the manufacturer using an EAD, which is proven by an ETA.
- ETA: Evaluates products according to European standards (EADs) for wider use in the EU.
- DIBt: Evaluates manufacturers and products, exclusively for the German market.
Questions about ETA at Langmatz
Does an ETA also have advantages in Germany?
Yes, the ETA offers transparency, comparability and standardised test criteria, which saves time and provides a clear overview of performance.
The ETA is useful to prove performance for use.
Why did Langmatz opt for an ETA?
The ETA and the Declaration of Performance give Langmatz comparable documentation which additionally defines the features of a stable manhole body and thus represents a new standard for manhole systems in the EU.
- German General Building Inspectorate Approval (AbZ) is restricted to Germany, while Langmatz operates internationally.
- There is no harmonised standard for the complete manhole.
Does the ETA change the quality of Langmatz products?
Langmatz test scenarios, which apply nationally and Europe-wide, provide our customers with the certainty and transparency of having purchased a safe and reliable product. We can also guarantee that the Langmatz range of “QualityBox” polycarbonate manholes does what its name promises.
Reason:
- The German General Building Inspectorate Approval is a national approval, but Langmatz operates Europe-wide
- There is no standard for the complete manhole (harmonised standard - hEN)
- We wish to offer our customers maximum transparency in their tenders
- Dual marking is not permitted (Ü or CE)
Are the ETA and DIBt equivalent?
Both test scenarios give the customer certainty about the construction product they have purchased. In Germany, both certifications (AbZ and ETA with ABG) are equal. It is up to the manufacturer alone to decide whether to apply for an ETA for their construction product or whether to pursue a national approach with a General Building Inspectorate Approval. The General Building Inspectorate Approval test requirements are not publicly accessible, while the EAD requirements can be viewed. This allows customers to stipulate relevant requirements in specifications and compare products.
