In steel structures factory, the biggest challenge for floor systems is not only load-bearing capacity, but also vibration stability, long-span capability, and construction optimization. This is exactly why SP Deck technology was developed — representing a major advancement beyond traditional deck slab systems.
1. What Is the Real Role of the Steel Deck Sheet in SP Deck?
Many people mistakenly believe that the steel deck sheet is the main load-bearing component of the floor system. In reality, within the SP Deck structure, the steel deck sheet plays very little role in primary load-bearing.
Its main functions are:
- Replacing traditional formwork during concrete pouring
- Retaining concrete and mortar without leakage
- Creating a flat bottom surface for the slab
- Connecting to the steel frame through welding points
The steel sheet is corrugated and embossed to:
- Increase bonding between concrete and steel
- Create strong connection points with the steel truss system
- Reduce slippage between concrete and steel layers under load
In other words, the steel deck sheet in SP Deck acts more like a “permanent formwork layer” rather than the primary structural component.
2. Where Does the Actual Load-Bearing Capacity of SP Deck Come From?
The superior load-bearing performance of SP Deck comes from its high-strength triangular steel truss system positioned above the deck sheet. This is the true “structural core” of the entire flooring system.
High-Density Triangular Steel Truss Structure
SP Deck utilizes:
- High-strength steel bars
- Spatial triangular truss connections
- Much denser truss arrangements compared to conventional deck systems
The triangular structure is the most stable geometric form in structural mechanics, helping to:
- Distribute loads evenly
- Reduce floor deflection
- Increase overall stiffness
- Minimize vibration during use
This is especially important for pre-engineered steel buildings, which inherently tend to:
- Vibrate easily
- Create a “bouncy” floor feeling
- Experience oscillation under dynamic loads
SP Deck solves these issues by creating a highly rigid floor system through:
- Continuous triangular truss structures
- Integrated steel-concrete connections
- Efficient composite structural behavior
- Khả năng làm việc composite hiệu quả

3. Why Does SP Deck Reduce Vibrations Better Than Traditional Deck Slabs?
Floor vibration mainly depends on:
- Structural stiffness
- Natural vibration frequency
- Deflection under load
In conventional deck slabs:
- The deck sheet is relatively thin
- Rib spacing is larger
- Structural stiffness relies heavily on hardened concrete
Meanwhile, SP Deck features:
- An actively load-bearing triangular steel truss system
- Increased stiffness even before concrete pouring
- Multiple connection points between concrete and steel framing
This helps to:
- Significantly reduce walking vibrations
- Minimize resonance effects
- Provide a more solid and stable floor feel
SP Deck is particularly effective for:
- Pre-engineered steel buildings
- Large-span office spaces
- Industrial factories with dynamic loads
- Projects requiring highly stable flooring systems
4. Long-Span Capability — One of SP Deck’s Strongest Advantages
One of the most outstanding technical advantages of SP Deck is its ability to achieve longer spans under the same live load conditions.
This means:
- The same usage load
- The same slab thickness
- But SP Deck can span greater distances between beams
This is possible thanks to:
- The high stiffness of the steel truss system
- Efficient internal force distribution
- Effective deflection reduction
- Enhanced composite action between steel and concrete
Practical Benefits of Longer Spans
With greater spanning capability, projects can:
- Reduce the number of secondary beams
- Optimize structural steel quantities
- Increase usable space
- Reduce overall structural height
- Accelerate construction progress
This is a major advantage for:
- Industrial buildings
- Showrooms
- Shopping centers
- Open-plan offices
- High-rise steel structures

SP Deck is becoming an ideal solution for projects
5. SP Deck Is Not Just a “Deck Sheet” — It Is a Complete Composite Flooring System
The most important thing to understand is that SP Deck is not simply a steel deck sheet.
Instead, it is:
- A fully integrated composite flooring system
- Combining steel decking + load-bearing steel trusses + bonded concrete
- Functioning as a unified structural system
This integration delivers:
- Exceptional stiffness
- High load-bearing capacity
- Effective vibration reduction
- Long-span performance
- Optimized construction efficiency
In today’s trend toward industrialized construction, SP Deck is becoming an ideal solution for projects requiring:
- Fast construction speed
- Lightweight structures
- Large spans
- High stability
- Optimized lifecycle costs

Trong kết cấu nhà thép hiện đại, bài toán lớn nhất của hệ sàn không chỉ nằm ở khả năng chịu tải, mà còn ở độ ổn định dao động, khả năng vượt nhịp và tối ưu thi công. Đây chính là lý do công nghệ SP Deck ra đời như một bước tiến vượt xa so với các hệ sàn deck truyền thống.
1. Tấm tôn nền của SP Deck thực sự có vai trò gì?
Nhiều người thường hiểu sai rằng lớp tôn nền là bộ phận chịu lực chính của hệ sàn. Thực tế, trong cấu tạo SP Deck, tấm tôn nền gần như không đóng vai trò chịu lực chính.
- Thay thế cốp pha truyền thống trong quá trình đổ bê tông
- Giữ nước và vữa bê tông không bị rò rỉ
- Tạo mặt đáy phẳng cho sàn
- Liên kết với hệ khung thép thông qua các điểm hàn
Tấm tôn được cán sóng và dập gân nổi nhằm:
- Tăng độ bám dính giữa bê tông và thép
- Tạo vị trí liên kết chắc chắn với hệ xương thép
- Hạn chế hiện tượng trượt lớp giữa bê tông và thép khi chịu tải
Nói cách khác, lớp tôn nền của SP Deck đóng vai trò như một “lớp khuôn vĩnh cửu” hơn là bộ phận chịu lực chính.
2. Bộ phận chịu lực thực sự của SP Deck nằm ở đâu?
Khả năng chịu lực vượt trội của SP Deck đến từ hệ xương thép tam giác cường độ cao phía trên lớp tôn nền. Đây mới là “trái tim kết cấu” của toàn bộ hệ sàn.
Cấu trúc xương thép tam giác mật độ cao
SP Deck sử dụng:
- Hệ thanh thép cường độ cao
- Liên kết theo dạng giàn tam giác không gian
- Mật độ bố trí dày hơn nhiều so với deck thông thường
Cấu trúc tam giác là dạng hình học ổn định nhất trong cơ học kết cấu, giúp:
- Phân phối tải trọng đồng đều
- Giảm biến dạng võng sàn
- Tăng độ cứng tổng thể
- Hạn chế rung động khi sử dụng
Đây là điểm cực kỳ quan trọng đối với nhà thép tiền chế - vốn có nhược điểm cố hữu là:
- Dễ rung
- Cảm giác sàn “bồng bềnh”
- Dao động khi có tải động
SP Deck giải quyết vấn đề này bằng cách tạo ra một hệ sàn có độ cứng rất cao nhờ:
- Hệ giàn tam giác liên tục
- Liên kết đồng bộ giữa thép và bê tông
- Khả năng làm việc composite hiệu quả

SP Deck với hệ xương thép tam giác mật độ cao
3. Vì sao SP Deck giảm rung động tốt hơn sàn deck truyền thống?
Rung động sàn phụ thuộc chủ yếu vào:
- Độ cứng hệ kết cấu
- Tần số dao động riêng
- Độ võng khi chịu tải
Ở sàn deck thông thường:
- Tôn deck mỏng
- Khoảng cách gân lớn
- Độ cứng phụ thuộc nhiều vào bê tông sau khi đông kết
Trong khi đó, SP Deck có:
- Hệ xương thép tam giác chịu lực chủ động
- Độ cứng tăng ngay từ trước khi đổ bê tông
- Liên kết nhiều điểm giữa bê tông và khung thép
Điều này giúp:
- Giảm đáng kể độ rung khi đi lại
- Hạn chế hiện tượng cộng hưởng
- Tăng cảm giác chắc chắn khi sử dụng
Đặc biệt hiệu quả với:
- Nhà thép tiền chế
- Văn phòng nhịp lớn
- Nhà xưởng nhiều tải trọng động
- Công trình yêu cầu sàn ổn định cao
4. Khả năng vượt nhịp lớn — lợi thế cực mạnh của SP Deck
Một trong những ưu điểm kỹ thuật nổi bật nhất của SP Deck là:
Khả năng vượt nhịp lớn hơn trong cùng điều kiện hoạt tải. Điều này có nghĩa:
- Cùng tải trọng sử dụng
- Cùng chiều dày sàn
- Nhưng SP Deck có thể vượt khoảng cách xa hơn giữa các dầm
Nguyên nhân đến từ:
- Độ cứng cao của hệ giàn thép
- Khả năng phân phối nội lực tốt
- Giảm võng hiệu quả
- Tăng khả năng làm việc composite giữa thép và bê tông
Lợi ích thực tế của vượt nhịp lớn
Khi vượt nhịp lớn hơn, công trình sẽ:
- Giảm số lượng dầm phụ
- Tối ưu khối lượng thép kết cấu
- Tăng không gian sử dụng
- Giảm chiều cao kết cấu tổng thể
- Thi công nhanh hơn
Đây là lợi thế rất lớn đối với:
- Nhà công nghiệp
- Showroom
- Trung tâm thương mại
- Văn phòng không gian mở
- Nhà thép cao tầng

SP Deck là môt hệ sàn composite tích hợp
5. SP Deck không chỉ là “deck” — mà là một hệ sàn composite hoàn chỉnh
Điểm khác biệt quan trọng nhất cần hiểu là:
SP Deck không đơn thuần là tấm deck thép.
Mà đây là:
- Một hệ sàn composite tích hợp
- Bao gồm tôn nền + hệ giàn thép chịu lực + bê tông liên kết
- Hoạt động như một kết cấu đồng nhất
Chính sự kết hợp này tạo ra:
- Độ cứng vượt trội
- Khả năng chịu tải cao
- Giảm rung hiệu quả

The cold storage industry requires steel structures to meet highly demanding technical standards to ensure stable and long-term operation under extreme environmental conditions. Beyond load-bearing performance, steel structures must provide excellent corrosion resistance and structural stability in low-temperature, high-humidity environments with continuous operation.

SEICO x YOKOREI: Steel Structure Solutions Meeting Cold Storage Industry Standards
One of the key challenges in cold storage facilities is thermal deformation caused by significant temperature differences between the inside and outside of the warehouse. As steel naturally expands and contracts with temperature changes, the structural system must be carefully engineered and fabricated to maintain durability, precision, and operational efficiency over time.
For the YOKOREI project, SEICO delivered high-precision steel structure solutions that fully satisfy the technical requirements of refrigerated, frozen, and cooling storage systems in accordance with Japanese and international standards.
