Investment Rating - The report maintains an "Outperform" rating for the construction materials sector, indicating expected performance above the market index by over 10% [7][77]. Core Viewpoints - The Xinjiang-Tibet Railway is anticipated to accelerate construction, with a total investment estimated between 300 billion to 400 billion yuan, and a construction period of 7-8 years. This project is expected to significantly boost demand in related industries such as cement, steel, and water-reducing agents [2]. - The construction materials sector is expected to benefit from the ongoing recovery in infrastructure investment, driven by key projects like the Xinjiang-Tibet Railway and the Yaxi Hydropower Station. The sector's valuation remains at a low point, suggesting potential for recovery in profitability [4]. - The report highlights the importance of supply-side adjustments and improving demand conditions, which are likely to create a positive feedback loop for the construction materials sector [4]. Summary by Sections Cement - National cement prices remained stable, with a recent increase of 20 yuan/ton in Henan and a decrease of 20 yuan/ton in Inner Mongolia. The average shipment rate is around 44%, with many prices touching or falling below cost lines due to rising coal prices [3][24]. - If self-regulatory measures are effectively implemented, cement prices may begin to recover [24]. Glass - The price of float glass has continued to decline, with reductions of 1-5 yuan per weight box in various regions. The production and sales rate has decreased, leading to increased inventory pressure [3][35]. - In the photovoltaic glass segment, prices have slightly increased due to improved downstream component operating rates and strong overseas demand, with 2.0mm coated panel prices rising to 10.5-11 yuan/square meter (+2.38%) [3][42]. Fiberglass - The price of non-alkali roving yarn has shown a slight decline, with mainstream prices at 3150-3700 yuan/ton, averaging 3521.25 yuan/ton, down 2.06% week-on-week [3][45]. Investment Recommendations - The report suggests focusing on cement and glass sectors, which are expected to benefit from supply-side adjustments and improving demand. Specific companies recommended include Qibin Group, Conch Cement, Huaxin Cement, and Tapai Group [4]. - For fiberglass, the report highlights opportunities driven by structural demand increases, particularly in high-end applications related to AI [4]. Construction Sector - The construction sector has seen a decline in new orders and profitability due to local governments focusing on debt reduction. However, infrastructure investment is expected to recover in the second half of the year, with new government bonds directed towards new projects [5]. - Recommended companies in the construction sector include China Railway Construction, China Communications Construction, and China State Construction [5].
