WORLDSTEEL IS THE FIRST COMPANY IN ASIA ACHIEVING IAS AC472 CERTIFICATION!

IAS Accreditation for Metal Building Systems Inspection (AC472)

Verification that approved manufacturers meet requirements as described in Chapter 17 of the IBC.
The benchmark for companies that design and manufacture engineered metal building systems.
Provides a level of confidence that buildings will be designed and manufactured according to code and specifications.
Recognized by the Metal Building Manufacturers Association (MBMA) and International Code Council (ICC).

BENEFITS TO THE BUILDING OWNER

Owners purchasing building products from non-IAS AC472-accredited metal building manufacturers may be taking a risk, buying products which may not necessarily meet their long-term best interest. Building owners have found that purchasing a building from an accredited manufacturer has provided the following:

Compliance with special inspection requirements in Chapter 17 of the International Building Code®.
Expedited acceptance of plans by code officials.
Better protection for occupants and contents.
Lower insurance rates.
Lower maintenance costs.
Lower utility costs.
Better resale value.

WHAT IS PRE-ENGINEERED STEEL BUILDING ?

Pre-Engineered Steel Building is structural steel building built over three members connected to each other:

The primary members: columns, rafters, bracing,…
The secondary members: Z or C purlins, girts, eave struts,…
Roof and wall sheeting: roof and wall panels, interior roof and wall liners, soffit panels… A complete solution for PB project includes

PRE-ENGINEERED STEEL BUILDING DESIGN STANDARDS

All projects are designed and manufactured following the latest US standards:

AISC 360 -10: 2010 Specification for Structural Steel Buildings
AWS Dl.1/Dl .1M: 2015 (2nd Printing) Structural Welding Code-Steel
MBMA 2012: 2012 Metal Building Systems Manual
IBC 2015: 2015 International Building Code

We can apply other international design standards based on your requirements.

WHY CHOOSE PRE-ENGINEERED STEEL BUILDINGS?

Overall price

Price per square meter can be 25% lower than conventional steel building

Structure weight building

+ About 30% lighter through the-efficient use of steel. Primary framing members are tapered varying depth built-up plate sections with large depths in the areas of highest stress.

+ Secondary members are light gage (light weight) cold formed (low labor cost) “Z” – or “C” shaped members. Z purlins / girts can be lapped.

+ Lapping reduces the deflection, and allows double thickness at the points of higher stresses (support points)

Quality Control

Designed and fabricated in-house with strict quality control. The fabrication process is controlled from start to finish, including design and engineering, as well as detailing and manufacturing at factory

DELIVERY TIME

+ PB can be delivered within 6-8 weeks.

+ About 30-50% times saving in total project schedule due to fast delivery and quick site erection

Erection cost & time

+ Site erection cost is low because of faster erection times and easier erection process.

+ Erection costs & time are accurately known, based upon extensive experience with similar buildings.

Architecture

+ PB can be applied for complex structures and highly aesthetic projects.

+ Based on its compact structure, PB is suitable for various forms of long span and highly aesthetic structure characterized by simple and effective steel structures.

+ These buildings use standardized materials that have been proven to meet a variety of structural and aesthetic require-ments and the components are engineered beforehand.

Erection Simplicity

+ The column and rafter components of PB are I beams which are linked by bolts and braced by simple bracing systems. So the erection process is fast, step by step, easy to install and require minimum heavy equipment.

+ In particular, as the PB column itself is highly stable, we don’t need to use complex as many bracing system as CB.
