Qingdao Regions Trading Co., Ltd (Qingdao Climber) is a professional manufacturer and exporter specializing in corrugated steel culvert pipes and structural plates. With over 10 years of experience in international markets, the company supplies AASHTO standard corrugated steel culvert to Malaysia and many other countries worldwide.
What Is an AASHTO Standard Corrugated Steel Culvert?
An AASHTO standard corrugated steel culvert is a structural drainage pipe manufactured according to the specifications of the American Association of State Highway and Transportation Officials (AASHTO). These culverts are widely used in highway and civil engineering projects around the world due to their structural strength, reliability, and cost-effectiveness.
Corrugated steel culverts are manufactured from carbon steel plates that are corrugated to form a series of ridges and grooves. This corrugated structure significantly improves the pipe’s load-bearing capacity and resistance to soil pressure.
The corrugation design allows the pipe to distribute loads effectively, making it suitable for installation under roads, railways, and heavy traffic areas.
Key Characteristics
High structural strength
Long service life
Flexible structural design
Easy installation
Excellent corrosion protection
Because of these advantages, AASHTO standard corrugated steel culvert to Malaysia projects are widely used for stormwater drainage, culverts, small bridges, irrigation systems, and flood control infrastructure.
Why Corrugated Steel Culverts Are Ideal for Malaysia
Malaysia has a tropical climate with heavy rainfall throughout the year, which makes efficient drainage systems extremely important. Flood control and water management are major concerns in both urban and rural areas.
Corrugated steel culverts provide several advantages for Malaysian infrastructure projects:
1. Excellent Drainage Performance
Malaysia experiences frequent heavy rains and seasonal monsoons. Corrugated steel culverts efficiently channel stormwater and prevent water accumulation beneath roads and bridges.
2. Strong Load-Bearing Capacity
The corrugated structure provides exceptional strength, allowing the culvert to withstand heavy traffic loads and deep soil cover.
3. Long Service Life
With hot-dip galvanized coatings ranging from 610 g/m² to 1200 g/m², the culverts provide excellent corrosion resistance, even in humid tropical environments.
4. Cost-Effective Infrastructure Solution
Compared with reinforced concrete culverts, corrugated metal culverts are lighter, easier to transport, and faster to install, reducing construction time and overall project cost.
5. Modular Design for Overseas Shipping
Corrugated steel culverts are typically manufactured in modular plate segments, making them ideal for export. They can be shipped efficiently and assembled easily on site.
For these reasons, demand for AASHTO standard corrugated steel culvert to Malaysia has been steadily increasing in recent years.
Technical Specifications of AASHTO Corrugated Steel Culverts
Qingdao Climber manufactures AASHTO standard corrugated steel culvert pipes with a wide range of specifications to meet various engineering requirements.
Steel Materials
The steel plates used for culvert production include:
Q235B
Q345B / Q355
S235JR
S355JR
ASTM A36
These materials offer excellent strength, weldability, and durability for structural applications.
Steel Plate Thickness
Available steel plate thickness ranges from:
1.5 mm – 8 mm
The thickness is selected according to project requirements such as pipe diameter, fill height, and load conditions.
Pipe Diameter Range
Corrugated steel culverts are available in a wide range of diameters:
300 mm – 16,000 mm
This wide range allows engineers to select the most suitable pipe size for different drainage capacities and site conditions.
Corrugation Profiles
Corrugation profiles determine the strength and flexibility of the pipe.
Common corrugation types include:
68 × 13 mm
100 × 20 mm
125 × 25 mm
150 × 50 mm
200 × 55 mm
300 × 110 mm
380 × 140 mm
400 × 150 mm
Large corrugation profiles are often used for big diameter culverts and structural plate culverts.
Shape Options
To accommodate various engineering designs, corrugated steel culverts can be manufactured in several shapes:
Round
Arch
Oval
Pipe arch
Half round
These shape options provide flexibility for different drainage and bridge applications.
Assembly Types
Corrugated steel culverts are assembled using different connection methods:
Bolted plate assembly
Annular flanged connection
Nestable pipe sections
These designs allow fast installation and easy transportation.
Zinc Coating and Surface Treatment
Corrosion resistance is essential for long service life.
Steel plates are protected by hot-dip galvanization, with zinc coatings typically ranging from:
610 g/m² – 1200 g/m²
Additional bitumen coating may also be applied during culvert assembly to enhance corrosion protection.
Depth of Fill
Corrugated steel culverts can support a wide range of fill depths:
1.5 meters – 60 meters
This capability makes them suitable for both shallow drainage systems and deep embankment structures.
Service Life
With proper galvanization and maintenance, AASHTO standard corrugated steel culverts can achieve a service life of more than 70 years.
Manufacturing Process of Corrugated Steel Culverts
Producing high-quality AASHTO standard corrugated steel culverts involves several precise manufacturing steps.
1. Steel Plate Preparation
High-quality carbon steel plates are selected and inspected to ensure they meet required mechanical properties.
2. Corrugation Forming
The steel plates are passed through corrugation machines to create the required profile. This process increases the structural rigidity of the material.
3. Cutting and Punching
Plates are cut to precise dimensions and bolt holes are punched to allow accurate assembly.
4. Hot-Dip Galvanization
All steel plates undergo hot-dip galvanizing, forming a protective zinc layer that prevents corrosion.
5. Quality Inspection
Each batch undergoes strict quality control to ensure compliance with AASHTO M36 or JTT 791-2010 standards.
