Know About Metal Building Codes and Regulations

If you plan to build a metal structure, you must have come across the terms like metal building codes and permits. This topic is not very thrilling, but the law requires it. You must obtain these permissions before digging in for your foundation. A building permit is a license that allows you to erect a metal structure at the site. A zoning permit allows you to build a specific type of metal structure selected by you at the site. Building codes are different from permits.

So, you must be wondering, what are the building codes?

These laws define how metal structures and accessories like HAVC systems can be designed and installed on your construction site. In America, these codes vary with local region and state.

However, lawmakers do not make their codes from scratch. They start with a standard ‘model code,’ which they can modify as per the state’s requirement. The model code’s job is to provide safety guidelines from dangerous circumstances like fire, wind, snow, hail, rain, or other risks that buildings must withstand. 

These codes are documented by the non-profitable International Code Council (ICC) with the help of experts in relevant fields. In the US, NIST is an agency that plays a vital role in reviewing and updating codes. They research and probes building failures caused by human or natural disaster to enhance codes and standards. Organizations that specify structural steel and concrete design practices are the American Society of Civil Engineers (ASCE), ASTM International, and the National Fire Protection Association(NPFA). These institutions, along with ICC, identifies error or gaps in engineering and human error to upgrade the rules further. 

Previously, the building codes were maintained by National Building Codes (NBC), Uniform Building Codes (UBC), and Standard Building Codes (SBC). The majority of these codes were similar to each other. The federal government established the ICC to unify and simplify all these codes. Further, International Building Codes (IBC) was created by ICC.

Nowadays, most states in the US use IBC guidelines as a base. States can add their specific regulations. For example, Florida has rules concerning hurricanes, and California has rules for earthquakes. As a buyer of a prefab garage, you can get particular insurance discounts if your building meets or exceeds specific standards.

What are Metal Buildings Codes Requirements?

Design Loads

IBC’s current changes say that all metal structures should be held at the same requirement for wind load. The problem is not all buildings are the same, and neither they experience wind pressure in the same way. For example, a tall structure needs more stability during a heavy storm than a short and wide one. 

In Chapter 22, Steel, Section 2207.2, designs related to specific loads, such as net uplift, axial, concentrated, etc., are mentioned. Same chapter, Section 2205, structural steel requirements for seismic activities are mentioned.

Structural Integrity

Metal structures should be made using steel that meet the minimum requirement of that state’s metal building code. These are legally required and are non-negotiable. Since the metal comes in many grades and types, the IBC specifies them as a ‘reference.’ 

In ICC guidelines, Chapter 22 Steel, Section 2206 deals with composite structural steel and concrete structures. Same chapter, Section 2204 refers to various metal connections such as bolting, welding, and anchor rods.

Energy Codes

If you buy a prefab metal building, ensure it is well insulated. Since metal is a good conductor, not having insulation can lead to condensation, further promoting the growth of mildew, rust, and molds. Insulation also depends on your building’s type, location, and usage. Usually, metal building codes are similar to regular structures except for energy codes. 

Energy codes and minimum energy standards are essential to both suppliers and buyers. The model codes for energy standards are developed by ICC and are updated every three years. It covered rules for roofs and walls created by IECC and Standard 90.1. 

Metal buildings code restrictions vary from state to state. These include plumbing code, mechanical code, fire code, electrical codes, etc. Before buying your prefabricated garage, follow all state codes and permit processes. Building codes may look like mundane tasks to read, but they exist for safety reasons. These rules apply to many metal structures such as home, commercial buildings, prefab garage, public space, metal barns, and potential buildings where large gathering occurs.

Summary

When you buy a prefab garage, you must meet all the regulations before construction. Please do so to avoid a fine, delay in work, or, worst case, removal of your garages or other structures. Note that these rules are subject to the state where you live. If you find reading fine print tedious, you can outsource this to a professional who will care for your needs.
