Prefabricated Integral Staircase

Prefabricated integral staircase, that is, the whole part uses a fixed mold for casting molding.

Advantages: can produce many categories of products with good quality.

Prestressed concrete hollow slab (SP slab)

The prestressed concrete hollow slab has a width of 1200mm and an economic span of 8-12m.

Advantages: large span, low cost and convenient construction.

Prefabricated caisson

The surface flatness of the prefabricated caisson can be as flat as the surface of the mold or made into a groove effect. Through the change of the mold, rich and changeable shape can be realized, saving on-site mold making and expensive support.

Advantages: good waterproof and anti-seepage performance, saving on-site moulding and expensive support.

Prestressed Concrete Composite Slab (PK slab)

The prestressed laminated board has the advantages of no support or less support, and low steel consumption for some types.

Advantages: low cost, convenient construction, and can replace truss reinforced concrete laminated slabs.

Prefabricated concrete beam

The secondary casting concrete is divided into prefabricated laminated slabs and fully prefabricated beams, and different degrees of prestress are applied to reduce or even eliminate supports. Products often use C40 concrete, HRB400 grade ordinary steel bars, etc.

Advantages: custom-made precast concrete beams with different appearance qualities, and fair-faced concrete beams are free of plastering. The prestressed concrete beam has a large span and no cracks at the bottom of the beam.

Prefabricated balcony, air conditioner, bay window slab

Follow up the design requirements, and can produce prefabricated laminated balconies, air conditioners, and bay window slabs.

Advantages: can produce many categories of products with good quality.

Truss reinforced concrete laminated slab

The truss reinforced concrete composite slabs are produced using fluid concrete and assembly molds. Prefabricated composite slabs of different sizes and shapes can be produced according to project requirements.

Advantages: there are many categories of products with good quality, special-shaped slabs can be produced, and the product adaptability is high.

UHPC Decorative  Panel

Lightweight decorative wall panels made of high-performance concrete. It has high self-strength and does not require reinforcement by steel bars.

Cast-in-place sandwich insulation non-load-bearing exterior wall

It is a non-structural component that integrates the functions of enclosure, heat preservation, heat insulation, fire prevention, waterproofing and weather resistance.

Advantages: improve efficiency, energy saving, integrated building.

High-performance energy-saving soundproof doors and windows

Three-glass two-cavity structure doors and windows have good energy-saving properties, good thermal insulation performance, energy saving, doors and windows have good sound insulation, good air tightness, and effectively block the spread of noise.

Advantages: sound insulation, energy saving.

Prefabricated sandwich insulation non-load-bearing exterior wall

An important prefabricated component that integrates the functions of envelope, heat preservation, heat insulation, fire prevention, waterproofing, durability and quakeproof.

Advantages: ① stable quality and high precision; ② diversified exterior surface modeling; ③ can greatly shorten the construction period; ④ can realize the construction without external frame; ⑤ good fire protection effect; ⑥ no need to do external wall insulation, and the insulation layer and external decorative surface has the same life span as the structure, and almost no maintenance is required.

Light steel keel grout wall

It is a non-load-bearing board made of cement fiberboard and calcium silicate board as two panels, and a lightweight core material is filled in the middle. 

Advantages: ① light weight of the wall; ② good fire resistance; ③ good anti-seismic performance; ④ good sound insulation performance; ⑤ good thermal insulation; ⑥ 6 good wall integrity; ⑦ easy implementation of difficult walls; ⑧ strong hanging ability ⑨convenient construction; ⑩high installation accuracy; ⑾low carbon and environmental protection.

Pipe Gallery 

It is composed of columns, beams and trusses of steel or reinforced concrete structures. 

Advantages: high efficiency and good quality control.

Trench cover

Trench (well) cover made of steel grating

Advantages: a variety of models to choose from.

Road Traffic Stone

cast with mold and can be made of artistic concrete surface, imitation stone, insect erosion surface, corrosion surface, frosted surface, mirror surface and color can be diverse.  

Advantages: uniform color, no cracks on the surface, complete edges and corners, consistent appearance, no obvious spots and chromatic aberrations.
