Sprenger qulity concept

Sprenger - Part of Your Passion

For over 150 years, Sprenger has stood for precision Made in Germany. The passion for our work is also reflected in the quality of our products. Because we do our best every day to provide you with products that you can trust blindly.

Our SPRENGER products reflect the perfection that we put into every detail, no matter how small. The quality is achieved through a variety of trades in combination with a large quantity of modern and classic machinery and equipment. The final inspection and packaging of the finished product is a critical part of the normal daily function with the result that, in contrast to bulk production methods, the finished products will come in touch with the hands of a person.

The significance of Sprenger quality awareness is not only directed towards the products. Delivery and customer service are also very important in order to be a reliable partner for you at all times. We would like to communicate with you as equals, pass on our knowledge and experience to you and, at the same time, listen to your suggestions, wishes and ideas.

Choice of raw materials

The careful choice of raw materials provides Sprenger the important basis to satisfy the customer’s purpose of use and their technical and individual requirements. The wire properties play an important part in the process of manufacturing our dog collars. It is for this reason that Sprenger only work together with suppliers that are able to provide a constant quality confirmed by certification. If the material composition is out of specification then the wire will be rejected before entering production.

Breaking load

The production of the crude chain and the welding of the single links will be effected, depending on the type of chain, in one or two individual operations.  An electronic surveillance of the welding operation and the inspection of the tensile strength are part of the operational procedure as well as permanent documentation of the results. Each material and wire gauge has individual parameters whereby strict observation ensures the required strength is achieved. If the fall of the current differs from normal, or the automatic wire movement stalls, then the production process will be stopped automatically. Due to that operational process Sprenger is in the position to state guaranteed breaking loads for all chains and collars. Depending on the basic material and the wire gauge the tensile strengths differ significantly. In case of similar wire gauges a collar made of stainless steel features a higher strength than a collar made of CUROGAN or steel. Detailed information about the particular material and the tensile strengths of each chain relating to a dog’s weight limit for the type of collar is provided on the product pages.

Chachet Marking

The symbol of a quality “Made in Germany” will be defined by stamping the material with INOX / CUROGAN or the seal of approval HS-GERMANY on every ring of all Sprenger collars. In addition ULTRA-plates, swivels, toggles and hooks are also stamped with the quality seals “HS” or “SPRENGER”. A collar without the marking “HS-GERMANY” on the rings is without doubt not a Sprenger made product. With this branding we provide a clear disassociation from the poor quality of competitors on the markets. We are of the opinion that every dog is worthy to wear a Sprenger collar.

Stainless steel tag

Besides the stamp “HS-GERMANY INOX” on all rings of our collars made of stainless steel, Sprenger labels this premium material, whether polished or blackened, with an additional tag that is marked with a red dot on one side and Stainless Steel stamped on the other. With help of this tag it’s possible to differentiate a stainless steel collar from a chromed steel variety at first glance. This tag epitomises the collar’s highest strength, safety and durability. As a result of the seawater resistance and the rust proof characteristics, the Sprenger stainless steel collars represent the most proficient product for all life’s situations for your dog.

HS Quality Seal

With help of the quality seal “HS GERMANY”, Sprenger identifies the mark of the German production facility in Iserlohn, currently in the fifth generation. Sprenger is proud to manufacture in Germany with help of well trained employees and selected local suppliers to produce high quality products for the world market. This also provides an opportunity for the apprenticeship of junior employees through to valued and skilled personnel by supporting their career over time. The Sprenger seal of quality represents a commitment to excellence that ensures the confidence to acquire a reliable and long-lasting product based on environmentally conscious manufacturing.
