EN 10210 and EN 10219 are the two core standards for structural steel pipes in Europe, the main differences are reflected in the production process, performance characteristics and application scenarios, the specific analysis is as follows:
production process differences
1. EN 10210 (Thermoformed steel pipe)
• The use of thermoforming process: the steel is heated to high temperature after plastic deformation, after forming may be seamless or welding treatment, internal residual stress is small, the material toughness retention is good.
• Applicable process range: including hot rolling, hot extrusion or cold forming with heat treatment (to achieve the same metallurgical state as hot forming).
2. EN 10219 (Cold-formed steel pipe)
• Cold forming process: The steel plate is welded after bending and forming at room temperature without high temperature treatment, but it will produce large residual stress.
• Applicable process scope: cold forming welding only, and without heat treatment.
mechanical properties comparison
EN 10210 (Thermoforming):
Better toughness, strong impact resistance
Impact toughness for high dynamic loads (e.g. Bridges, offshore platforms)
Thermoforming reduces internal stress and reduces the risk of deformation
EN 10219 (Cold forming):
Cold working hardening effect makes the yield strength and tensile strength higher
Low impact toughness, suitable for static load scenarios
Cold forming causes large residual stress, and subsequent stability needs to be considered
Dimensions and tolerances
• EN 10210:
Materials may spring back after thermoforming, tolerances are slightly wider, but more adaptable to high load scenarios.
• EN 10219:
The dimensional accuracy of the cold forming process is higher and the surface is smoother, which is suitable for building frames, guardrails, etc., which require strict tolerances.
temperature adaptability
• EN 10210:
Good high temperature resistance, suitable for high temperature environments (e.g. boiler pipes, energy equipment).
• EN 10219:
Suitable for low or normal temperature environments only (e.g. building supports, photovoltaic structures).
Application fields
EN 10210:
bridges, offshore platforms, heavy machinery (cranes, mining equipment), high-temperature pipelines
EN 10219:
building frames, mechanical frames (conveying equipment, billboards), infrastructure (guardrail, scaffolding)
Certification and cost considerations
CE certification:
Both are part of the harmonized standards of the EU Construction Products Regulation (CPR) and are subject to review of the production control system by a notified body in a similar process.
Cost differences:
EN 10219 is usually more cost-effective due to the simplicity of the process; EN 10210 has higher cost but better performance due to the complex thermal forming process.
Summary selection suggestions:
Select EN 10210:
if high toughness, impact resistance or high temperature environments are required (e.g. heavy machinery, Bridges).
Select EN 10219:
for high precision, low cost and low environmental load (e.g. building supports, photovoltaic structures).
