Wangdue Phodrang tle:National Standards for Stair Tread Dimensions

e National Standards for Stair Tread Dimensions is a comprehensive guide that sets forth the minimum dimensions and specifications for stair treads. This standard aims to ensure safety, accessibility, and aesthetic appeal in stairs, with particular emphasis on the dimensions of treads and risers. The standards provide detailed guidelines for the width, height, and depth of treads and risers, as well as the placement of handrails and other features. These dimensions are designed to accommodate different types of stairs, including residential, commercial, and public buildings. By adhering to these standards, builders and designers can ensure that stairs meet the necessary requirements for safe and efficient use.

Introduction

Stairs are an essential part of any building, providing a safe and convenient means of access to different floors. The design and dimensions of stair treads play a crucial role in ensuring the safety and comfort of users. In this article, we will discuss the national standards for stair tread dimensions, including their classification, measurement methods, and compliance requirements.

Wangdue Phodrang Classification of Stair Tread Dimensions

There are several classifications of stair tread dimensions based on the type of stairs and the intended usage. Here are some common classifications:
