Products
Precast concrete is a versatile structural and architectural material and can be used as the structural system of a building or other structures. Precast structural systems are comprised of a variety of shapes and components. Most of these will fall into categories of beams, columns, slabs, walls and architectural precast concrete products. However, since precast is a cast material and is factory made, essentially any shape can be manufactured to meet a project's needs.
Beams
Beams are typically considered structural components and are made in one of three key shapes:
- Rectangular
- Inverted Tee Beams
- L-Beams
Beams are horizontal components that support deck members like double tees, hollow-core, solid slabs, and sometimes other beams. They can be reinforced with either prestressing strand or conventional reinforcing bars. This will depend on the spans, loading conditions, and the precast producer's preferred production methods.
Precast Concrete Joists, Beams, Girders, and Columns Small, closely spaced beams used in floor construction are usually called joists.
Typical Beams and Joists sizes: Practically any size needed to satisfy structural requirements.
Columns
Columns are typically used to support beams and spandrels in applications such as parking structures and precast concrete structural systems of all types. They generally are designed as multilevel components ranging from a single story to six levels or more. Sizes and shapes can vary to satisfy both architectural and structural requirements.
Typical shapes: Square or rectangle
Typical sizes: Practically any size needed to satisfy structural requirements
Finishes: Since columns are cast in a horizontal position, three of the four sides are created with a form. These finishes are very smooth and most often remain "as cast" in the finished construction, although they may have an architectural finish and be exposed to view if required.
Solid Slabs
Solid slabs are used as structural deck components similar to hollow-core slabs. They can be made in a long-line pre-tensioning facility and reinforced with prestressing strand or cast in individual forms with either prestressing strand or conventional reinforcing bars. They are typically cast in the same position as used in the structure.
Typical sizes: Practically any size needed to satisfy structural requirements
Finishes: The form side (bottom) is smooth as cast and typically will remain that way in the finished construction. When it is an exposed surface, it can remain as is or painted without additional treatment. The top side is troweled to the desired degree of smoothness or may be intentionally roughened to receive a cast-in-place concrete topping that will act compositely and provide additional strength.
Architectural Precast Concrete
Architectural precast concrete is generally defined as any precast product that contributes to the aesthetic and architectural value of the structure. Products include buildings, wall or panel systems, sound barriers, picnic tables, ornamental pieces, signs, support slabs, columns and so forth. In most cases, besides versatility and durability, the use of architectural precast products results in cost and time savings for the project
Insulated Wall Panels
Each panel consists of two reinforced precast concrete wythes with a continuous layer of insulation sandwiched in between. With a selection of patterns, surface treatments and colour choices our insulated precast/prestressed wall panel system offers an economical opportunity for our clients to incorporate their unique corporate identity into their office, warehouses, storage facilities, residential and many more.
Precast Wall Panels
Solid wall panel refers to walls being made of solid concrete as opposed to including integral insulation. Sometimes these wall systems require some form of insulation and an interior wall/finishing system to complete the building enclosures.
Typical sizes: Practically any size needed to satisfy structural requirements
Finishes: Since wall panels are cast in a flat orientation, the form side is typically the side that will be exposed to view in the final construction. This face can be made with virtually any type of finish. The back face is commonly troweled smooth or may have a light broom finish.
Concrete Fire Walls
The Twin Valley precast concrete firewall system is a fast track construction method for fire containment walls providing up to 2- 4 hours fire rating. The precast concrete panels span between building columns to produce foundation free, smooth, firewalls which in addition can perform the duties of security or retaining walls.
Alternatively, the precast firewall units may be used vertically to produce fire containment compartments within clear spans of buildings. Precast concrete panels are manufactured to suit individual requirements and are available in a range of widths. The flexibility of manufacture enables the precast wall panels to be produced to almost any size to suit the building layout. The precast concrete firewall panels are manufactured in different thicknesses (design specification) and various fire exposure ratings.
Retaining Walls
Precast concrete manufacturers produce a wide range of engineered earth retaining systems designed to provide a straightforward and cost-effective solution for your next project. Issues with wall height, right-of-way, seismic activity, drainage, quality control and aesthetics can all be overcome with a precast concrete earth retaining system.
Silage Bunkers
Twin Valley bunker silo offers large volume storage capacity system, the lowest cost per ton silage, and the lowest initial investment and the lowest Total Cost of Ownership (TCO). Unlike a silo bag, silage bunker silos are a more economical, one-time investment way to reduce spoilage. Storing feed in a Twin Valley bunker silo can save a producer over 50% less spoilage- dry matter loss verses ground pile storage.
Feed Troughs
In addition to Water Troughs Twin Valley manufactures a comprehensive range of durable precast concrete Feed Troughs suitable for use with dairy and beef cattle. Our livestock feed troughs are suitable for use with diet feeders ensuring food stuffs are kept clean and within livestock reach at all times.
Jersey Barriers
Our precast concrete jersey barriers feature forklift slots at the bottom for easy portability when used to direct traffic during road construction. Excellent for keeping construction workers safe from oncoming vehicles and designed to minimize vehicle damage in the event of a collision by allowing the vehicle be lifted when riding up on the lower slope and then redirected. Ideal for anywhere public safety and security is a priority. These jersey barriers are made to offer maximum durability and minimum maintenance an are rebar reinforced.
