What Are the Steps in the Production Process of UHPC Exterior Wall Decorative Lines — Detailed Analysis and Key Steps Guide

In the field of building construction, component stacking may seem simple, but it is in fact a crucial aspect affecting project quality, construction safety, and efficiency. Especially for new architectural decorative materials such as UHPC, GRC, GRG, and GRP, a scientific and standardized stacking method not only protects material performance but also lays a solid foundation for the subsequent installation stage. As an industry-leading enterprise with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the core principles and practical key points of component stacking from a professional perspective.

I. Safety First: Building a Solid Construction Safety Line

The primary principle of component stacking is to ensure safety. Whether it is the high-strength characteristics of UHPC exterior wall panels or the diverse shapes of GRC decorative lines, the basic requirements of "stable load-bearing, anti-tipping, and collision prevention" must be strictly followed. When undertaking large projects, Qinglong Group typically requires the stacking site to be flat and solid, with load-bearing capacity sufficient for the weight of the components. For GRG ceiling components exceeding 1.5 meters in height, dedicated supports must be used for layered stacking, with cushion pads placed between layers to prevent edge and corner damage caused by compression. Meanwhile, in view of the hot and humid environments common in overseas projects, Qinglong covers GRP daylighting roof components with rain protection to prevent environmental impact on material performance.

II. Classified Management: The Key to Improving Efficiency

The different properties of materials determine differentiated stacking methods. UHPC components, due to their ultra-high strength and durability, can be stacked vertically to save space; GRC components need to be stacked by model and size for easy access during construction; GRG materials, due to their gypsum-based properties, must be protected from moisture, and the stacking area needs to be kept ventilated and dry; GRP components need to be protected from direct sunlight to prevent aging. Qinglong Group implements "digital stacking management" at its Nanning production base, coding components through BIM technology combined with RFID chips for tracking and positioning, ensuring that all types of materials are stacked in an orderly manner and reducing secondary handling costs. This management model has been successfully applied to multiple landmark projects in China.

III. Performance Protection: The Guardian of Material Quality

New building materials have more stringent requirements for the stacking environment. For example, UHPC components must avoid long-term compression that could cause micro-cracks during stacking; Qinglong adopts the "three-point support method" to ensure uniform stress distribution. The texture and color on the surface of GRC components are the core of the decorative effect, so they need to be wrapped in PE film during stacking to prevent scratches; the curved shapes of GRG components require custom-made dedicated support blocks to avoid deformation. As an enterprise that participated in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong has always integrated material protection throughout the entire stacking process, ensuring that every product delivered to the construction site meets quality standards.

IV. Process Coordination: A Seamless Transition from Stacking to Installation

Scientific stacking planning should be closely integrated with the construction schedule. When undertaking commercial complex projects, Qinglong Group stacks components on a "first-in, first-out" basis according to the installation sequence to reduce on-site transfers. For overseas projects such as a GRP roofing project at an airport in Malaysia, installation efficiency was improved by 30% through advance planning of stacking areas and hoisting paths. This full-chain thinking not only reflects Qinglong's integrated advantage of "detailed design + production + construction" but also ensures controllable quality from the factory to the final forming of the project.

As an "invisible project" in building construction, the standardization of component stacking directly reflects an enterprise's professional strength. Qinglong Group's 28 years of industry experience is reflected not only in the technological innovation of UHPC/GRC/GRG/GRP materials but also in every detail of construction management. From domestic landmark buildings to key overseas projects, Qinglong has always maintained a meticulous attitude of striving for excellence, transforming scientific stacking principles into a guarantee of engineering quality and laying a solid foundation for the mission of "creating beautiful architecture". In the future, with the widespread application of new materials, standardized and intelligent stacking management will become a key lever for improving project quality and efficiency, and Qinglong will continue to play its industry-leading role in driving the continuous upgrading of application standards for architectural decorative materials.
