ABSTRACT A gutter system of thermoplastics material is provided for mounting to a wall, the gutter system comprising a plurality of hanger brackets and gutter sections, each hanger bracket comprising a mounting plate for mounting the hanger bracket on a wall, a beam secured to the mounting plate and extending therefrom to an end remote the mounting plate, a downwardly opening channel carried by the beam proximate the mounting plate, the channel having a reduced or restricted mouth portion for receiving and securing a resiliently deformable lip carried on the top of the front and rear wall of each gutter section which lip deforms when pressed through the mouth of the channel into the channel and resiliently restores for locking in the channel, the beam preferably being in the form of an I-beam and more preferably in the form of a modified I-beam being triangular in shape with a taller web portion proximate the mounting plate than remote the mounting plate, the gutter comprising front and rear walls and a bottom, the top of the rear wall comprising a resiliently deformable lip (preferably in the form of a V-shaped lip) for being inserted and secured in the channel, by being pressed through the restricted channel mouth portion into the channel to expand therein and be precluded from being removed until resiliently depressed to be removed through the channel mouth, complementary fastening elements at the end of the beam remote the mounting plate and on top of the front wall of the gutter for securing together, and a raised bead or projection on the inner surface of the rear wall extending in the same direction as the lip on the top of the rear wall and spaced therefrom whereby when the lip is in the channel, and the complementary fastening elements secured, the beam proximate the mounting plate of each hanger bracket engages the bead or projection on the rear wall of the gutter to rigidify the structure and permit ease of expansion and contraction of the gutter sections relative to the hanger brackets supporting the gutter sections, and the mounting plate spaces the rear wall of the gutter sections from the wall to which the gutter system is secured to ease expansion and contraction of the gutter sections.
