for stainless steel structurals 3 Hot Rolling Extrusion Laser Fusion


HOT ROLLING

Equal Leg Angles

Advantages

+ Good availability

+ Well known products

- Limited choice of profiles

- High tooling cost for new profiles

- High quantity required for rolling

+ Most cost effective technology

Disadvantages

1


EXTRUSION

Seamless Tubes & Custom Profiles

Advantages

+ Hollow shapes

+ Small batch sizes

- Limitations on wall thickness

- Limited size range

- Long lead times

+ Complex geometries

Disadvantages

2


LASER FUSION

Beams Channels Angles - Tees

Advantages

+ High flexibility on profile design

+ Small batch size

- Little known technology

- Higher production cost + High quality product

Disadvantages

What makes Laser Fusion so unique compared to conventional welding?

Crash test on Laser fused H beams achieved official product standard:


Availbility of Stainless Steel Structurals

Equal Angles 15x15x2 - 400x400x20 mm

Miscellaneous Channels 40x20x3 - 250x125x15 mm

T Bars 20x20x3 - 150x150x15 mm

Unequal Angles 20x10x3 - 400x200x20 mm


I Beams 80 - 600 mm

Standard Channels 50 - 400 mm

Universal Beams 100 - 900 mm

H Beams 100 - 1000 mm


What has changed?

improved distribution network new technologies availability of small quantities complete size range

Yesterday

Today

few suppliers long delivery time limited size range limited know how irregular consumption

This evolution enables architects and engineers to plan & design freely with

stainless steel like they use to do with carbon steel.


Stainless Steel Standards

EN

DIN

BS

ASTM

JIS

Easy availability of stainless steel structural sizes according to ASTM, EN and

JIS in South East Asia


Common and special Stainless Steel types

Standard sizes are stocked in the two most common austenitic stainless steel

types:

304/L 316/L Other special grades like Heat Resistant, Duplex, Super Duplex or Super

Austenitic stainless steel get frequently specified for projects and can be

sourced from specialized producers.
