As the Southern region of Vietnam enters the peak of the 2026 rainy and stormy season, ensuring absolute safety for industrial infrastructure and production activities is the top priority for investors. For large-scale factory complexes like the LIXIL Manufacturing Factory – a renowned global brand in sanitary ware and building materials, any water leakage from the roof can lead to severe damage to assets, high-tech machinery, and interrupt the manufacturing supply chain.
Recognizing this core importance, the management of LIXIL Factory has trusted and selected Chuan A Company – a leading prestigious enterprise in the field of industrial construction, mechanical-electrical, and fire fighting systems (FFS) – as the official contractor to execute the item: Replacing the degraded existing rain water gutter system with a premium Stainless Steel gutter system.
This article records in detail the actual construction log at the site on June 23, 2026, analyzing the technical solutions, occupational safety measures, and updating the progress towards the expected handover date.
On June 23, 2026, the weather in the construction area was relatively complex. However, thanks to careful preparation and contingency plans, Chuan A's team of engineers and workers deployed the work smoothly and precisely.
The factory's old gutter system, after years of enduring harsh weather, showed signs of aging and heavy rusting at the joints, causing localized leaks during heavy rains.
The dismantling process required extreme caution not to affect the structure of the roof sheets and the surrounding purlins. Chuan A's workers proceeded to:
Cut off old anchoring points using specialized hand cutters.
Lower the old gutter sections to the ground using a safe pulley system, preventing any impact on the factory's glass facades or enclosure walls.
Clean up the purlins supporting the gutters to prepare the ground for the next phase.
Immediately after the ground was cleared, the technical team re-measured the elevation using a laser leveling machine to ensure optimal drainage slope. The new gutters are fabricated from thick, high-quality Stainless Steel (SUS 304), which offers absolute corrosion resistance against the acidity of industrial rainwater and can withstand strong winds.
The installation process included:
Positioning the brackets and gutter hangers securely onto the steel beam system of the factory.
Lifting the stainless steel gutter modules into position, aligning the overlapping joints by 10-15cm according to industrial construction standards.
Using specialized drilling and screw-fastening machines to fix the gutters, combined with weather-resistant structural silicone sealant at the joints to completely eliminate the risk of water leakage.
For a project requiring operations at heights (factory roof maintenance), Chuan A always places occupational safety as the number one priority. The personnel organizational chart at the site on June 23, 2026, included:
01 Site Supervisor (GS): Responsible for checking design drawings, inspecting joint quality, urging progress, and especially controlling pre-shift safety for the entire area.
05 Skilled Workers (CN): All of whom are construction mechanical workers holding certificates for working at heights, with extensive practical experience in large-scale factory projects.
Supported Handheld Mechanical Equipment System:
Handheld Cutters: Used to trim the profile of old gutters and edge-finish new stainless steel sheets to fit tightly with the roof structure.
Drilling and Bolt-Tightening Machines: Ensuring the tightening force fixing the gutters to the steel beam system reaches maximum load-bearing capacity, preventing flapping or shaking during storms.
Scaffolding systems, full-body safety harnesses, and safety nets: Ensuring 100% of workers operating at heights are strictly protected.
By the end of the working day on June 23, 2026, the actual completed workload reached 30% of the total contract volume. This is a very positive figure, demonstrating the site organization capacity and high craftsmanship of the Chuan A worker team.
Expected Handover Date: June 30, 2026.
Plan for the Remaining 70% Workload: In the following days, Chuan A will increase manpower if the weather turns bad, focusing on completing the roof rainwater hoppers, connecting the new gutter system to the existing vertical drainage downspouts, and conducting water testing (leakage check) for the entire system before official inspection and handover to LIXIL Group.
The successful and on-time deployment of the gutter replacement item at LIXIL Factory once again affirms the position and professional competence of Chuan A Company. We do not just build sturdy industrial projects; we protect them from all harsh impacts of time and weather through professional maintenance and repair services. With the philosophy of putting the quality and safety of our clients first, Chuan A is proud to be a reliable companion of multinational corporations in Vietnam.
