The safety on our roads is priceless, and guardrails are the crucial barrier that helps mitigate loss from serious accidents. Choosing a guardrail is therefore not just about the price, but an investment in the lives and assets of every road user. This article will take you through why you should only choose guardrails certified by the Thai Industrial Standards Institute (TISI) 248-2567 and Department of Highways (DoH) Standards. We will also decode the international production process we use to deliver products that ensure maximum confidence.

1. Why is "Standardization" the Heart of Guardrails? Guardrails installed on the road must fulfill two functions: "absorbing impact" and "redirecting" vehicles that lose control. Without strict standards, the components might bend or fracture during an accident, which could lead to an even more severe hazard.

• TISI Standard 248-2567 (Guardrails on Highways): This is the latest standard certifying the chemical, mechanical, and physical properties of the materials, from the steel used in manufacturing to the galvanizing process. This TISI mark guarantees that the product can perform its safety function and maintain durability in various environments.
• Department of Highways (DoH) / Department of Rural Roads (DRR) Standards: These are detailed requirements that specify the dimensions, forming patterns, spacing of bolt holes, and the thickness of the zinc coating. All of these factors significantly affect Impact Performance and ease of installation, in line with highway safety engineering principles.

2. Decoding Confidence: The Production Process under ISO 9001 High-standard guardrail products originate from a production process where quality is meticulously controlled at every stage, governed by the international quality management system, ISO 9001. We utilize this system to ensure that every component achieves maximum precision and durability.
Measurable Safety Choosing a guardrail that meets TISI 248-2567 and DoH standards guarantees that the product has passed proven testing and production processes. Do not take risks with sub-standard guardrails, because in the event of an unexpected incident, the structural integrity of the guardrail is the difference between a minor accident and a tragedy.

Choose products from "LEKISE" that are certified with the international quality standard ISO 9001 and TISI 248-2567 for "Peace of Mind and Safety on Every Road."
