Optimized steel utilization for retaining walls
Z-shaped sheet piles place steel further from the neutral axis to deliver bending resistance, enabling wall assemblies to resist lateral soil and water loads. Section modulus and moment of inertia serve as critical engineering parameters to evaluate structural performance. The real load capacity of a sheet pile wall relies on design loads, ground conditions, support layout, embedment depth and adopted design codes.
Continuous interlocked wall system
Z sheet piles join together via interlocks to build a seamless wall structure. Interlock shape, installation quality and assembled wall state all affect overall system performance. For projects requiring groundwater containment, engineers need to define interlock performance criteria, sealing solutions and construction methods. Steel grade alone cannot guarantee water tightness.
Applicable to both temporary and permanent works
AZ profiles fit many earth retention and marine projects. The classification of a wall as temporary or permanent is determined by engineering design, intended service life, corrosion exposure and specific project requirements.
Royal Steel Group can supply different AZ sheet pile profiles according to project requirements.
Common selection parameters include:
AZ profile
Width
Height
Flange thickness
Web thickness
Weight per meter
Weight per square meter of wall
Moment of inertia
Elastic section modulus
Plastic section modulus
Required pile length
For example, published AZ section data includes profiles such as AZ 18, AZ 18-10/10 and AZ 26, with different dimensions, weights and section properties.

Royal Steel Group can discuss sheet pile orders according to the requested grade, standard, dimensions, and inspection requirements.
Potential grades to include in the purchasing discussion:
| Grade | Purchasing consideration |
| S270GP | Confirm applicable standard and mechanical requirements |
| S355GP | Higher nominal yield-strength category; confirm certification |
| S390GP | Confirm specified standard, chemistry, and mechanical properties |
| S430GP | Confirm grade availability and required documentation |
| Q235B / Q355B | Use only when the applicable GB specification is explicitly required |
Important note: Availability of each listed grade for AZ 26-700 is not guaranteed. Material grade confirmation is required prior to formal production. EN 10248 and GB standards carry separate requirements for chemical composition, mechanical properties and dimensional tolerances.
Retaining Walls
Deployed for both permanent and temporary earth retention structures to contain lateral soil pressure.
Cofferdams
Well suited for temporary construction enclosures for foundation, bridge, port and waterway projects.
Deep Excavation
Serves as excavation support systems for underground works and foundation construction.
Marine Construction
Works for quay walls, waterfront developments, riverbank stabilization and other structures subject to soil and hydrostatic pressure.
Port & Infrastructure Projects
Thanks to its wide profile and high structural efficiency, AZ sheet piles are a reliable option for large infrastructure schemes.
Depending on project specifications and applicable standards, AZ sheet piles can be supplied in commonly requested grades such as:
S240GP
S270GP
S320GP
S355GP
S390GP
S430GP
Q235B / Q355B
For each project, the required grade should be confirmed against the engineer's design, applicable standard, and purchasing specification rather than selecting a grade based only on nominal strength.
Common project lengths can be supplied according to engineering requirements, including 6 m, 9 m, 12 m, 15 m and 18 m. Custom lengths can also be discussed for project orders.
For longer retaining walls, the actual pile length should be determined from:
Excavation depth
Soil conditions
Groundwater level
Surcharge loads
Required embedment depth
Bending moment
Corrosion allowance
Temporary or permanent use
AZ 26-700 sits within the AZ-700 series and can be considered alongside profiles such as AZ 24-700 and AZ 28-700. The published data shows increasing section height, weight, moment of inertia, and section modulus as the profile number increases.
| Profile | Width | Height | Weight | Section Modulus |
| AZ 24-700 | 700 mm | 241 mm | 95.7 kg/m | 2,430 cm2/m |
| AZ 26-700 | 700 mm | 242 mm | 102.9 kg/m | 2,600 cm2/m |
| AZ 28-700 | 700 mm | 243 mm | 110.0 kg/m | 2,760 cm2/m |
These published profile values can help buyers and engineers compare sections during preliminary selection. Final selection should follow the project's structural calculations.
