Weath­er­proof pro­tec­tion for roof steps wanted

The com­pa­ny Heuel und Söhne GmbH man­u­fac­tures roof ele­ments that enable safe access to roofs. For their cast alu­minum roof steps, stain­less steel struc­tures are screwed onto roof plat­forms. This cre­ates the pos­si­bil­i­ty
of rain­wa­ter enter­ing the roof.


A rub­ber coat­ing was designed to pre­vent water from enter­ing, keep­ing the roof dry at the point of drilling.


Jäger Gum­mi und Kun­st­stoff, as a long­stand­ing devel­op­ment part­ner, was com­mis­sioned with an addi­tion­al solu­tion for the rub­ber mat on the roof step, as the mat was becom­ing detached from the roof step foot over time.

Solu­tion

Per­fect mate­r­i­al knowl­edge for fur­ther development

The mate­r­i­al com­pound used to date for the EPDM sup­port mat was adopt­ed for the new addi­tion­al cov­er, but its Shore hard­ness was changed. This ensures imper­me­abil­i­ty and also increas­es the ser­vice life of the prod­uct. The experts pro­duced a pro­to­type of the new cov­er using a 3D print­ing process.

 

Jäger Gum­mi und Kun­st­stoff, togeth­er with Heuel, car­ried out the first test of the pro­to­type on the stain­less steel foot. For this pur­pose, the new cov­er was pulled over the stain­less steel leg of the plate and, togeth­er with the mat, cov­ers the com­plete foot. Sub­se­quent­ly, the pro­to­type was exten­sive­ly test­ed in prac­tice at the customer’s site.

Dry roofs thanks to EPDM protection

After suc­cess­ful­ly pass­ing the tests, the EPDM cov­er for the roof steps went into series pro­duc­tion. In the mean­time, the com­po­nent, which appears small at first glance, has already ensured tight bore­holes and thus dry house roofs on many roofs.
