Roof ElementsProducts
A gutter beam is a U-shaped precast member that sits on the columns along the eaves or at the valley between adjacent bays. It acts as a structural beam while collecting rain and meltwater and channeling it to the downpipes.
A gutter beam is a precast beam with an open-topped U-section that collects roof water. It sits on the columns along the eaves line or, in multi-bay buildings, along the internal valley where two roofs meet.
A gutter beam does two jobs at once:
This reduces the need for a separate edge beam and a separate metal gutter, keeping the roof edge detail simpler.
In factories and warehouses made up of several adjacent bays, gutter beams along the internal valleys are the key element for draining water that gathers in the middle of the roof. Sizing the gutter for rainfall and snow loads and planning the outlets correctly along these lines is critical to the safety of the roof.
The width, depth and length of a gutter beam are set jointly in the structural and plumbing designs, based on the volume of water to be handled, roof area, snow load and column spacing. A suitable waterproofing system is applied on site to the inside of the gutter and to the joints. Depending on the project, water is taken to ground level by downpipes running inside or alongside the columns, and the openings for the outlets are formed during production.
Gutter beams are cast in U-section molds, complete with connection sleeves and outlet openings. On site, they are lifted by crane onto the column heads or corbels and secured with dowel connections. The joints between elements are closed with grout or a suitable joint material before waterproofing.
The concrete gutter body itself is durable, but leaves, dust and snow build-up can block the flow of water. Seasonal cleaning of gutters and outlets, along with regular checks on the waterproofing, keeps the roof performing reliably for many years.
Dimensions, reinforcement and load capacity are set by structural design for each project; contact us for technical details.
Technical Guide
Precast concrete is a method in which reinforced concrete elements are made in a factory and erected on site by crane. This guide covers production, key elements, benefits and limits.
Technical Guide
Precast erection means lifting factory-made columns, beams and roof elements into place on site and connecting them. We cover every step from preparation to final checks, crane safety and the factors that determine erection time.
Investment Guide
A checklist for precast concrete warehouse investments: when to settle span, height, cranes, ground conditions, seismic design, snow load, fire safety and permits.
Prefabricated Plant Construction
We build factories, warehouses and industrial plants as a single contractor, from design to erection. Columns, beams, roof and facade elements are produced in our plant, delivered in planned sequence and erected by our own crews.
Facade and Floor Elements
A precast facade panel is a reinforced concrete wall unit made at the plant and fixed to the precast frame of an industrial building. It gives the building a durable, non-combustible envelope that goes up quickly.
Infrastructure Elements
A precast concrete pile is a reinforced or prestressed foundation element made in the plant and driven into the ground on site. It carries building loads past weak upper soil layers down to firmer strata.
