When Shixinda's factory produces this China Embedded Steel Plate, it uses Q235B, Q355B steel and HRB400 anchor bars. Relying on factory standardized prefabrication production, the dimensions are precise, the welds are stable, and after professional anti-corrosion treatment, it is corrosion-resistant and has a long service life. The hot-dip galvanized product has a service life of up to 30 years or more.
Compared to post-installed anchor bolts, this product does not require drilling and planting, does not damage the main structure, can significantly shorten the construction period, and has stronger tensile and shear bearing capacity, stable load-bearing, excellent seismic performance, and controllable positioning errors within the millimeter range.
The product strictly complies with JGJ 102 industry standards, has a high acceptance rate, and offers both standardized spot production and non-standard customization services.
No damage to the main structure, higher safety: Unlike the post-installed anchor bolt drilling construction which may break the main bars, damage the concrete, and cause cracking, Shixin Da's pre-installed plates are embedded synchronously with the concrete pouring. The structure is formed as a whole without any construction defects, and the strength of the building's main structure is completely retained.
Simplified construction process, cost reduction and efficiency improvement: The pre-installed parts are precisely placed once, and there is no need for drilling, planting, or waiting for the curing of the adhesive. Only bolt connection or welding is required to complete the installation. Taking the curtain wall project as an example, it can shorten the installation time of a single point by over 50%, significantly reducing the project duration.
Strong mechanical bearing capacity, stable and controllable force: Relying on the mechanical interlocking and bonding of the anchor bars and concrete, the tensile, shear, and uplift performance far exceed those of expansion anchors and chemical anchors. The force mode is clear, meeting the precise structural calculation requirements of engineers, and suitable for high-load engineering scenarios.
Factory standardized prefabrication, stable quality control: Abandoning the quality fluctuations in on-site operations, Shixin Da adopts industrialized batch production. The weld seam process, size tolerance, and anti-corrosion coating thickness all undergo strict quality inspection, and the product qualification rate and consistency far exceed those of on-site processed products.
Excellent cost performance throughout the life cycle: The single-piece purchase cost is slightly higher than that of post-installed accessories. However, from the perspective of the entire project cycle, there are no rework, secondary testing, later reinforcement, or rust maintenance costs. It has outstanding economic performance in long-term use under corrosive and humid conditions.
The conventional M20 anchor bolt pre-installed components have an anti-tensile force of 60–100 kN and an anti-shear force of 40–80 kN; the single-point anti-tensile bearing capacity of a 20mm thick Q345B galvanized pre-installed plate exceeds 500 kN; the bearing capacity of the optimized bottom pre-installed node can be more than 1.2 times the full-section yield bearing capacity of the beam. The products with bent hooks have excellent ductility and energy absorption capabilities, suitable for first-level safety structures, and the seismic design comes with a safety factor of 1.1 times.
Our Embedded Steel Plate uses a dedicated positioning mold and temporary support fixation process. The positional, elevation, and levelness errors are controlled within ±3–5mm, perfectly adapting to high-precision connection scenarios such as steel structure column feet, precision equipment foundations, and super high-rise curtain walls.
The standard hot-dip galvanized layer is ≥80μm, with a service life of up to 30 years; for high-corrosion environments such as marine, chemical, and sewage, 316L stainless steel material can be customized to completely eliminate the risk of rust.
Standardized + customized dual mode: We have full-scale standard spot products ranging from 100×100mm to 500×500mm, supporting rapid batch supply; at the same time, we can undertake non-standard customization such as drilling holes, slotting, bending, stiffening plates, and special dimensions, suitable for personalized engineering needs.
Strictly following the industry standard "Technical Code for Glass Curtain Wall" (JGJ 102), it conforms to the mainstream construction specifications of curtain walls and steel structures, can replace post-installed anchor bolts, avoid post-installed construction acceptance risks, and has complete documents and smooth acceptance.
Building curtain walls (main application): Used for connecting and fixing all types of curtain wall joists (glass, stone, aluminum plate), accounting for 60% - 70% of the overall application. It is suitable for super high-rise curtain walls and can optimize the wind vibration fatigue performance. Each square meter of the unit-type curtain wall can be adapted to 1 - 2 standard products.
Steel structure construction projects: Used for anchoring the column feet of frame-core tube buildings such as office buildings and hotels, as well as connecting beam-column nodes, secondary beams and supports. It can bear bending moments, axial forces and horizontal shear forces. The usage of each floor of a high-rise building can reach hundreds of pieces.
Transport infrastructure projects: Suitable for bridge bearings, expansion joints, high-speed rail ballastless track plates, subway platform screen doors, station rain shelters and other key infrastructure projects. Customized Q355B large-sized thickened embedded plates can be provided, suitable for heavy-load scenarios such as cross-sea bridges.
Industrial and equipment foundations: Widely used in factory equipment bases, tower crane foundations, pipeline fixation supports, data center vibration reduction bases, etc. It can adapt to dynamic response conditions and avoid equipment resonance issues.
Municipal and public welfare projects: Covering stair railings, balcony railings, parking shelters, billboards, lamp posts foundations, underground pipe racks, etc. as municipal supporting facilities.
Emerging green building scenarios: Suitable for photovoltaic support base foundations and prefabricated building prefabricated component connection nodes, simplifying on-site construction processes, without the need for secondary pouring and curing, significantly reducing the construction period of prefabricated buildings.
