In order to seal gutters at the ends with low output, an end wall () of a gutter () is provided for surface drainage, comprising a plate element () which can be secured at a first or a second end of the gutter () substantially sealingly closing a cross-section of the gutter (). In addition, the ends () of the gutter () are formed differently. According to the invention, in order to reduce the output, the plate element () can be secured at the first end () of the gutter () with a first edge () oriented upwards or can be secured at the second end () with a second edge () oriented upwards. In this way, an adjustment can be made to both differently formed ends () of the gutter () by simply rotating the plate element.

End wall for a gutter for surface drainage

Covers for drains, manholes or similar constructions are known which comprise a first grate () made of sheet metal and comprising slots () and struts (), said struts having top faces () and each strut having side faces () made of sheet metal bent with respect to the top face. In order to increase the rigidity it is proposed that at least a second grate () is provided, the struts () of which are inserted in the slots () of the first grate ().

Covering consisting of a plurality of gratings inserted one into another

A stable and variable design of a drainage structure includes a drainage body () and a cover (). The cover () has engagement devices (') when seen in a longitudinal direction of the drainage body (), whereby the cover connects upper edges (&#x2032;) of the drainage body () to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers () for different loads, for example while using the same drainage body (), two types of engagement devices (&#x2032;) are provided on the drainage body.

Drainage channel with a drainage body and a cover

A cover grating for a drainage channel or a similarly hollow body which can be installed in the ground is presented, wherein the cover grating is produced in a single piece and more particularly from a sheet metal strip, comprising at least two longitudinal webs extending on the underside of the cover grating and inlet slots formed in the cover grating between these longitudinal webs and comprising transverse webs resulting from the slot forming operation and extending on the lower side of the cover grating wherein the transverse webs are provided at each of their end regions with at least one receiving projection which at least partially engages in to a respective complementarily formed receiving slot in the longitudinal web.
