1. Product Overview The High-Strength Q355B Pre-Engineered Steel Building (PEB) is a
high-performance, cost-effective industrial and commercial building
solution, integrating Q355B high-strength steel material,
large-span structural design and advanced anti-corrosion protection
technology. As a mainstream choice for modern industrial plants,
warehouses, logistics centers and large-span venues, it is
pre-designed, pre-fabricated in the factory and assembled on-site,
which realizes the integration of efficiency, durability and
environmental protection, and is widely applicable to global B2B
procurement needs, especially for projects with strict requirements
on structural safety, construction cycle and service life. 2. Core Material: High-Strength Q355B Steel Q355B steel is the core material of this pre-engineered steel
building, which is far superior to ordinary steel in mechanical
properties and applicability, and fully meets international and
national standards (GB 50017-2003, ISO standards), making it the
preferred material for high-demand steel structure projects: Excellent Mechanical Properties: The yield strength reaches
≥355MPa, and the tensile strength is 470-630MPa, with high
toughness and uniform material properties, which can bear large
loads and resist deformation, effectively ensuring the structural
stability of large-span buildings. Strong Adaptability: It has good cold resistance (can be used
normally at -20℃) and weldability, and can be processed into
various structural components (I-beams, C-section steel, Z-section
steel, etc.) according to design requirements, adapting to
different architectural shapes and functional needs. Cost-Effective: Compared with traditional steel materials, Q355B
steel has higher strength-to-weight ratio, which can reduce the
usage of steel, save material costs, and at the same time reduce
the self-weight of the building (only 1/3-1/2 of concrete
structures), lowering the foundation load and foundation
construction costs.
3. Core Feature 1: Large-Span Design Based on the excellent performance of Q355B steel, the product
adopts scientific structural design, breaking the space limitation
of traditional buildings, and is especially suitable for scenarios
requiring large open space, with the following advantages: Super Large Span Capacity: The span can be customized from 15m to
80m (even larger span can be realized by truss design), without
middle columns, maximizing the utilization of internal space, which
is ideal for large-scale warehouses, production workshops,
logistics centers, stadiums and other venues. Stable & Safe Structure: The primary framing structure is
composed of welded I-beams (tapered according to load distribution)
and bolted connections, with excellent seismic and wind resistance
performance — it can withstand seismic fortification intensity of
7-9 degrees (complying with ISO 16670) and wind speed up to 25m/s,
ensuring structural safety even in harsh environments. Flexible Space Layout: Without middle load-bearing columns, the
internal space can be freely divided and adjusted according to
actual needs (such as production areas, storage areas, office
areas), adapting to the upgrading and transformation of different
industries and process adjustments.
4. Core Feature 2: Advanced Anti-Corrosion Protection Aiming at the problem of steel structure corrosion (which affects
service life and safety), we adopt a three-in-one advanced
anti-corrosion system, combining factory pre-treatment and on-site
protection, to ensure long-term durability of the building,
complying with ISO 12944 and GB/T 15957 standards: Pre-treatment: All steel components are subjected to shot blasting
derusting to Sa2.5 level (surface roughness 40-75μm) in the
factory, removing oil, rust and oxide scale, laying a solid
foundation for anti-corrosion coating. Core Coating System: Adopt "epoxy zinc-rich primer + epoxy
micaceous iron intermediate paint + fluorocarbon/polyurethane
topcoat" system — zinc-rich primer (zinc content ≥80%) forms the
first anti-corrosion barrier, intermediate paint increases coating
thickness and shielding performance, and topcoat provides excellent
weather resistance and decoration, effectively resisting acid rain,
salt fog, industrial pollution and ultraviolet radiation. Optional Reinforced Protection: For harsh environments (coastal
areas, chemical industrial zones), hot-dip galvanizing treatment
can be added, which further improves corrosion resistance, making
the service life of the building reach 50-100 years, and reducing
long-term maintenance costs. Strict Quality Inspection: After coating, each component is tested
for film thickness (complying with "90-10" rule), adhesion and
appearance, ensuring no missing coating, sagging or pinholes, and
the anti-corrosion effect is stable and reliable.
