Quality is not just another word for us.
We can prove it.

Trust is okay, but verification is better. Don’t just take our word for it.

We have full affirmation of our standards. 


(Reg.-No. Q1 0103040)
These accolades show that we take customer satisfaction rather seriously. The things that we do every day to make ourselves a little bit better are published in a quality management guide for all to see.  

Because we can prove that our quality is of the highest standard with DIN EN ISO 9001, you are not requested to just take our word for it.

Certificate DIN EN ISO 9001


A close relationship with universities, universities of applied science and industry associations constantly expands our knowledge about the conveyance of bulk materials. Our curiosity and our ambition drive us forward and enable us to tirelessly research and optimise our products, ensuring that our customers can be absolutely sure of the quality of our products.

CE Marking

We make our quality visible. The CE marking of our tube chain conveyors clearly shows that the conformity of our systems corresponds to the requirements of the European Union.
With the CE marking, we declare that our tube chain conveyor, as an individual installation, fulfills all the applicable community rules and that all mandated conformity assessment procedures (such as risk assessment, hazard analysis, and verification of compliance with the standards) have been carried out.

Welding Certificate as per DIN EN ISO 3834-2

(Reg.-No. W3 0103040)
Now it is official: We fulfill all the quality requirements according to the DIN EN ISO 3834 series of standards for the production of fusion-welded components and structures. This includes welding during made-to-order production as well as during assembly and service. This is yet another contribution on our part to the quality assurance of our products.

This is another certificate for plants or equipment used in production facilities in Russia with a high risk profile.
The RTN permit is issued by the Federal Service for Ecological, Technological, and Atomic Supervision ROSTECHNADZOR (formerly GGTN – GOSGORTECHNADZOR).
The certificate proves that our tube chain conveyors are not subject to this permit and, therefore, they do not require the certificate.
RTN Negative Clearance

EAC Certificate

The EAC certificate confirms that our tube chain conveyors have been presented to an accredited authority of the customs union and that they comply with all the technical regulations. It is proof that our conveyor systems fulfill the minimum requirements and do not require certification as
per TR-ZU. It is valid in Russia, Republic of Belarus, and Kazakhstan.

Hygiene certificate

This certificate is also only valid in Russia; however, this one is mandatory. It certifies that Schrage´s products fulfill all the necessary technical requirements corresponding to Russia`s hygiene standards.  
Hygiene certificate


...is not a certificate, but rather a directive that Schrage also uses at their location in Friedeburg, Germany: The ATEX directive 2014/34/EZ (previously 94/9/EG or “ATEX 95”) defines the regulations for putting into circulation products for use in environments with explosive atmospheres. It serves the purpose of protecting those who work in such environments. Therefore, the directive stipulates the fundamental health and safety requirements which must be met by the manufacturer. Here at Schrage, not only do we work in compliance with this directive, but we also fulfil the quality assurance system for the manufacturing, final acceptance and testing of conveyor systems and components which will be used in environments with explosive atmospheres.
